`
`Notice of Pre-AIA or AIA Status
`
`The present application, filed on or after March 16, 2013, is being examined under the first
`
`inventor to file provisions of the AIA.
`
`Continued Examination Under 37 CFR 1.114
`
`A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR
`
`1.17(e), was filed in this application after final rejection. Since this application is eligible for continued
`
`examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the
`
`finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's
`
`submission filed on 3/6/2020 has been entered.
`
`Response to Amendment and Arguments
`
`The Amendment filed 3/6/2020 has been entered. Claims 1 and 2 are amended. Claims 1-9 are
`
`currently pending in this application.
`
`Applicant’s arguments, see Pages 5-6, filed 3/5/2020, with respect to the rejection(s) of claim(s)
`
`1-6 have been considered but are moot. Regarding limitations of the instant case in view of the
`
`amended Claims and upon further considerations, a new ground(s) of rejection, necessitated by the
`
`amendments is made in view of different interpretation of the previously applied references and/or new
`
`prior art as presented in this Office action.
`
`In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102
`
`and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory
`
`basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and
`
`the rationale supporting the rejection, would be the same under either status.

`
`Claim Rejections - 35 USC § 103
`
`The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections
`
`set forth in this Office action:
`
`A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is
`not identically disclosed as set forth in section 102 of this title, if the differences between the claimed
`invention and the prior art are such that the claimed invention as a whole would have been obvious
`before the effective filing date of the claimed invention to a person having ordinary skill in the art to
`which the claimed invention pertains. Patentability shall not be negated by the manner in which the
`invention was made.
`
`Claims 1-2 and 4-7 are rejected under 35 U.S.C. 103 as being unpatentable over Kakinuma et
`
`al. (US 2009/0115713) in view of Chae et al. (US 2018/0045866) and Lee et al. (US 2014/0043566).
`
`Regarding claim 1, Kakinuma et al. teaches a liquid crystal display device (Fig. 9, [0205-0210,
`
`0189, 0162, 0147, 0141]) comprising:
`
`a first display panel (the front panel, 340 and the real panel in Fig. 9) including a first substrate
`
`(20 in Fig. 9, [0207]), a second substrate (10 in Fig. 9, [0207]) that is disposed in a first direction (the
`
`direction toward the upmost viewing surface in Fig. 9) with respect to the first substrate (20 in Fig. 9,
`
`[0207]) and includes a color filter (358 in Fig. 8, which is corresponding to 58 in Fig. 3, [0205, 0142]), and
`
`a first liquid crystal layer (340 in Fig. 9, [0207]) disposed between the first substrate (20 in Fig. 9, [0207])
`
`and the second substrate (10 in Fig. 9, [0207]);
`
`a color conversion unit (the unit corresponding to 351/352/353 in Fig. 9, which in corresponding
`
`to 51/52/53 in Fig. 3, [0205-0206, 0190, 0122-0123, 0054]) disposed in a second direction (the direction
`
`toward the backlight in Fig. 2) opposite to the first direction (the direction toward the upmost viewing
`
`surface in Fig. 9) with respect to the first display panel (the front panel, 340 and the real panel in Fig. 9);
`
`and
`
`a backlight (60 in Fig. 9, [0205-0206, 0209, 0254, 0054]) disposed in the second direction (the
`
`direction toward the backlight in Fig. 2) with respect to the color conversion unit (the unit corresponding
`
`to 351/352/353 in Fig. 9, which in corresponding to 51/52/53 in Fig. 3, [0205-0206, 0190, 0122-0123]),
`
`

`

`Application/Control Number: 16/168,394
`Art Unit: 2871
`
`wherein
`
`Page 4
`
`the color filter (358 in Fig. 8, which is corresponding to 58 in Fig. 3, [0205, 0142]) includes a first
`
`color filter ([0142]) of a first color ([0142]) and a second color filter ([0142-0143]) of a second color
`
`([0142-0143]),
`
`a black matrix (Fig. 9 and 3, [0068, 0142], the black matrix between blue, green and red color
`
`filters 358) is disposed at a boundary (Fig. 9 and 3, [0068, 0142]) between the first color filter (Fig. 9 and
`
`3, [0142]) and the second color filter (Fig. 9 and 3, [0142]) on the second substrate (10 in Fig. 9, [0207]),
`
`the color conversion unit (the unit corresponding to 351/352/353 in Fig. 9, which in
`
`corresponding to 51/52/53 in Fig. 3, [0205-0206, 0190, 0122-0123]) converts backlight light (Fig. 9)
`
`emitted from the backlight (60 in Fig. 9, [0205-0206, 0209, 0254]) into light of a color (Fig. 9, Fig. 3,
`
`[0122-0123, 0142-0143, 0205-0206, 0190]) corresponding to the color filter (358 in Fig. 8, which is
`
`corresponding to 58 in Fig. 3, [0205, 0142]), and emits the light (Fig. 9),
`
`the color conversion unit (the unit corresponding to 351/352/353 in Fig. 9, which in
`
`corresponding to 51/52/53 in Fig. 3, [0205-0206, 0190, 0122-0123]) includes:
`
`a first color conversion layer (353 in Fig. 9, which in corresponding to 53 in Fig. 3, [0205-0206,
`
`0190, 0122-0123]) that converts the backlight light (Fig. 9) into light of the first color (Fig. 9, Fig. 3,
`
`[0122-0123, 0142-0143, 0205-0206, 0190]);
`
`a second color conversion layer (352 in Fig. 9, which in corresponding to 52 in Fig. 3, [0205-0206,
`
`0190, 0122-0123]) that converts the backlight light (Fig. 9) into light of the second color (Fig. 9, Fig. 3,
`
`[0122-0123, 0142-0143, 0205-0206, 0190]); and
`
`a light shielding unit (354 in Fig. 9, which in corresponding to 54 in Fig. 3, [0190, 0123]) that is
`
`disposed at a boundary (Fig. 9 and 3) between the first color conversion layer (353 in Fig. 9, which in
`
`corresponding to 53 in Fig. 3, [0205-0206, 0190, 0122-0123]) and the second color conversion layer (352
`
`

`

`Application/Control Number: 16/168,394

`
`Page 5
`
`in Fig. 9, which in corresponding to 52 in Fig. 3, [0205-0206, 0190, 0122-0123]) and blocks transmission
`
`of light (Fig. 9 and 3, [0190, 0123]);
`
`a height (Fig. 9) of the light shielding unit (354 in Fig. 9, which in corresponding to 54 in Fig. 3,
`
`[0190, 0123]), and a height (Fig. 9) of the first color conversion layer (353 in Fig. 9, which in
`
`corresponding to 53 in Fig. 3, [0205-0206, 0190, 0122-0123]) and the second color conversion layer (352
`
`in Fig. 9, which in corresponding to 52 in Fig. 3, [0205-0206, 0190, 0122-0123]);
`
`a width (Fig. 9) of the black matrix (Fig. 9 and 3, [0068, 0142], the black matrix between blue,
`
`green and red color filters 358) disposed at the boundary (Fig. 9 and 3, [0142]) between the first color
`
`filter (Fig. 9 and 3, [0142]) and the second color filter (Fig. 9 and 3, [0142]); and a width (Fig. 9) of the
`
`light shielding unit (354 in Fig. 9, which in corresponding to 54 in Fig. 3, [0190, 0123]) disposed at the
`
`boundary (Fig. 9) between the first color conversion layer (353 in Fig. 9, which in corresponding to 53 in
`
`Fig. 3, [0205-0206, 0190, 0122-0123]) and the second color conversion layer (352 in Fig. 9, which in
`
`corresponding to 52 in Fig. 3, [0205-0206, 0190, 0122-0123]).
`
`Kakinuma et al. does not teach that the height of the light shielding unit is higher than the
`
`height of the first color conversion layer and the second color conversion layer, and the width of the
`
`black matrix disposed at the boundary between the first color filter and the second color filter is greater
`
`than the width of the light shielding unit disposed at the boundary between the first color conversion
`
`layer and the second color conversion layer.
`
`Chae et al. teaches that a height (Fig. 1-2) of a light shielding unit (120 in Fig. 1-2, [0035-0037]) is
`
`higher (Fig. 1-2) than a height (Fig. 1-2) of a first color conversion layer (140 in Fig. 1-2, [0038-0040]) and
`
`a second color conversion layer (150 in Fig. 1-2, [0038-0040]).
`
`Before the effective filling date of the claimed invention, it would have been obvious to the
`
`artisan of ordinary skill to employ that a height of a light shielding unit is higher than a height of a first
`
`color conversion layer and a second color conversion layer as taught by Chae et al. for the system of
`
`

`

`Application/Control Number: 16/168,394
`Art Unit: 2871
`
`Page 6
`
`Kakinuma et al. such that the height of the light shielding unit of the system of Kakinuma et al. is higher
`
`than the height of the first color conversion layer and the second color conversion layer of the system of
`
`Kakinuma et al. since this would help that color mixture is prevented to thereby increase color
`
`reproducibility. Also, light efficiency is increased, thereby reducing power consumption (Chae et al.,
`
`[0106]).
`
`Kakinuma et al. already teaches that the width (Fig. 9) of the black matrix (Fig. 9 and 3, [0068,
`
`0142], the black matrix between blue, green and red color filters 358) disposed at the boundary (Fig. 9
`
`and 3, [0142]) between the first color filter (Fig. 9 and 3, [0142]) and the second color filter (Fig. 9 and 3,
`
`[0142]); and the width (Fig. 9) of the light shielding unit (354 in Fig. 9, which in corresponding to 54 in
`
`Fig. 3, [0190, 0123]) disposed at the boundary (Fig. 9) between the first color conversion layer (353 in
`
`Fig. 9, which in corresponding to 53 in Fig. 3, [0205-0206, 0190, 0122-0123]) and the second color
`
`conversion layer (352 in Fig. 9, which in corresponding to 52 in Fig. 3, [0205-0206, 0190, 0122-0123]).
`
`Kakinuma et al. also teaches that the black matrix (Fig. 9 and 3, [0068, 0142], the black matrix between
`
`blue, green and red color filters 358) disposed at the boundary (Fig. 9 and 3, [0142]) between the first
`
`color filter (Fig. 9 and 3, [0142]) and the second color filter (Fig. 9 and 3, [0142]) is a light blocking
`
`member (Fig. 9 and 3, [0068, 0142]) formed on the second substrate (10 in Fig. 9, [0207]) and disposed
`
`at (Fig. 9, [0068, 0142]) a boundary (Fig. 9, [0068, 0142]) between adjacent subpixels (Fig. 9, [0068,
`
`0142]); and the light shielding unit (354 in Fig. 9, which in corresponding to 54 in Fig. 3, [0190, 0123])
`
`disposed at the boundary (Fig. 9) between the first color conversion layer (353 in Fig. 9, which in
`
`corresponding to 53 in Fig. 3, [0205-0206, 0190, 0122-0123]) and the second color conversion layer (352
`
`in Fig. 9, which in corresponding to 52 in Fig. 3, [0205-0206, 0190, 0122-0123]) is a partition between
`
`the first color conversion layer (353 in Fig. 9, which in corresponding to 53 in Fig. 3, [0205-0206, 0190,
`
`0122-0123]) and the second color conversion layer (352 in Fig. 9, which in corresponding to 52 in Fig. 3,
`
`[0205-0206, 0190, 0122-0123]). Kakinuma et al. in view of Chae et al. does not explicitly teach that the
`
`

`

`Application/Control Number: 16/168,394
`Art Unit: 2871
`
`Page 7
`
`width of the black matrix disposed at the boundary between the first color filter and the second color
`
`filter is greater than the width of the light shielding unit disposed at the boundary between the first
`
`color conversion layer and the second color conversion layer.
`
`Lee et al. teaches that a width (Fig. 1, 3 and 5) of a light blocking member (320 in Fig. 1, 3 and 5,
`
`[0036, 0054, 0061]) formed on the second substrate (310 in Fig. 1, 3 and 5, [0036]) and disposed at a
`
`boundary between adjacent subpixels (Fig. 1, 3 and 5, [0032, 0036, 0038]) is greater (Fig. 1, 3 and 5)
`
`than a width (Fig. 1, 3 and 5) of a partition (202 in Fig. 1, 3 and 5, [0038, 0044, 0053, 0060]) disposed at
`
`a boundary (Fig. 1, 3 and 5, [0038, 0044, 0053, 0060]) between a first color conversion layer (2013 in Fig.
`
`1, 3 and 5, [0038-0041]) and a second color conversion layer (201C in Fig. 1, 3 and 5, [0038-0041]).
`
`Before the effective filling date of the claimed invention, it would have been obvious to the
`
`artisan of ordinary skill to employ that a width of a light blocking member formed on the second
`
`substrate and disposed at a boundary between adjacent subpixels is greater than a width of a partition
`
`disposed at a boundary between a first color conversion layer and a second color conversion layer as
`
`taught by Lee et al. for the system of Kakinuma et al. in view of Chae et al. such that the width of the
`
`black matrix of the system of Kakinuma et al. in view of Chae et al. disposed at the boundary between
`
`the first color filter and the second color filter of the system of Kakinuma et al. in view of Chae et al. is
`
`greater than the width of the light shielding unit of the system of Kakinuma et al. in view of Chae et al.
`
`disposed at the boundary between the first color conversion layer and the second color conversion layer
`
`of the system of Kakinuma et al. in view of Chae et al. since this would help to divide a desired boundary
`
`of a plurality of pixels/subpixels and display the image having the desired color and brightness (Lee et
`
`al., [0036, 0015]).
`
`Regarding claim 2, Kakinuma et al. also teaches that the color conversion unit (the unit
`
`corresponding to 351/352/353 in Fig. 9, which in corresponding to 51/52/53 in Fig. 3, [0205-0206, 0190,
`
`

`

`Application/Control Number: 16/168,394
`Art Unit: 2871
`
`Page 8
`
`0122-0123]) further includes: a third substrate (330 in Fig. 9, [0207]) which the first color conversion
`
`layer (353 in Fig. 9, which in corresponding to 53 in Fig. 3, [0205-0206, 0190, 0122—0123]) and the
`
`second color conversion layer (352 in Fig. 9, which in corresponding to 52 in Fig. 3, [0205-0206, 0190,
`
`0122-0123]) are formed on (Fig. 9), and a band-pass filter (314 in Fig. 9, [0193, 0196, 0207], 314
`
`reflecting the second primary light and the third primary light, the first primary light (blue light) emitted
`
`from the light source passes through the third substrate 330 and the film 314) disposed on the third
`
`substrate (330 in Fig. 9, [0207]) in the second direction (the direction toward the backlight in Fig. 2) with
`
`respect to the first color conversion layer (353 in Fig. 9, which in corresponding to 53 in Fig. 3, [0205-
`
`0206, 0190, 0122-0123]), the second color conversion layer (352 in Fig. 9, which in corresponding to 52
`
`in Fig. 3, [0205-0206, 0190, 0122-0123]), and the light shielding unit (354 in Fig. 9, which in
`
`corresponding to 54 in Fig. 3, [0190, 0123]), the band pass filter (314 in Fig. 9, [0193, 0196, 0207], 314
`
`reflecting the second primary light and the third primary light, the first primary light (blue light) emitted
`
`from the light source passes through the third substrate 330 and the film 314) having a property of
`
`transmitting the backlight light and of reflecting the light of the first color and the light of the second
`

`
`the second primary light and the third primary light, the first primary light (blue light) emitted from the
`
`light source passes through the third substrate 330 and the film 314) is sandwiched (Fig. 9) with the light
`
`shielding unit (354 in Fig. 9, which in corresponding to 54 in Fig. 3, [0190, 0123]) and the third substrate
`
`(330 in Fig. 9, [0207]).
`
`Regarding claim 4, Kakinuma et al. also teaches that the backlight (60 in Fig. 9, [0205-0206,
`
`0209, 0254]) emits blue light ([0038-0039, 0054, 0121]), and the first color conversion layer (353 in Fig.
`
`9, which in corresponding to 53 in Fig. 3, [0205-0206, 0190, 0122—0123]) converts the blue light into red
`
`light (Fig. 9, [0054, 0121-0122], the third primary color is red), and the second color conversion layer

`
`(352 in Fig. 9, which in corresponding to 52 in Fig. 3, [0205-0206, 0190, 0122—0123]) converts the blue
`
`light into green light (Fig. 9, [0054, 0121-0122], the second primary color is green).
`
`Regarding claim 5, Kakinuma et al. also teaches that the backlight (60 in Fig. 9, [0205-0206,
`
`0209, 0254]) emits blue light ([0038-0039, 0054, 0121]), the color conversion unit (the unit
`
`corresponding to 351/352/353 in Fig. 9, which in corresponding to 51/52/53 in Fig. 3, [0205-0206, 0190,
`
`0122-0123]) includes a red conversion layer (353 in Fig. 9, which in corresponding to 53 in Fig. 3, [0205-
`
`0206, 0190, 0122-0123]) that converts a blue light into a red light (Fig. 9, [0054, 0121-0122], the third
`
`primary color is red) and a green conversion layer (352 in Fig. 9, which in corresponding to 52 in Fig. 3,
`
`[0205-0206, 0190, 0122-0123]) that converts the blue light into a green light (Fig. 9, [0054, 0121-0122],
`
`the second primary color is green), and the color filter (358 in Fig.8, which is corresponding to 58 in Fig.
`
`3, [0205, 0142]) includes a red color filter (Fig. 9, [0205, 0142-0143]) and a green color filter (Fig. 9,
`
`[0205, 0142-01431).
`
`Regarding claim 6, Kakinuma et al. also teaches that a polarizing plate (23 in Fig. 9, [0207]) is
`
`disposed between the color conversion unit (the unit corresponding to 351/352/353 in Fig. 9, which in
`
`corresponding to 51/52/53 in Fig. 3, [0205-0206, 0190, 0122—0123]) and the first display panel (the front
`
`panel, 340 and the real panel in Fig. 9).
`
`Regarding claim 7, Kakinuma et al. also teaches that the first display panel (the front panel, 340
`
`and the real panel in Fig. 9) is an IPS type liquid crystal display panel ([0032, 0053, 0171]).

`
`Claim 3 is rejected under 35 U.S.C. 103 as being unpatentable over Kakinuma et al. in view of
`
`Chae et al. and Lee et al. as applied to claim 1 above, and further in view of Song et al. (US
`
`2018/0088261).
`
`Re claim 3, Kakinuma et al. does not explicitly point out that each of the first color conversion
`
`layer and the second color conversion layer includes quantum dots having different diameters from
`
`each other.
`
`Song et al. teaches that (Fig. SB and 73, [0064-0069]) each of the first color conversion layer
`
`(141 in Fig. SB and 73, [0064-0069]) and the second color conversion layer (151 in Fig. SB and 7B, [0064-
`
`0069]) includes quantum dots (143 and 153 Fig. SB and 73, [0064-0069]) having different diameters
`
`from each other ([0067]).
`
`Before the effective filling date of the claimed invention, it would have been obvious to the
`
`artisan of ordinary skill to employ that each of the first color conversion layer and the second color
`
`conversion layer includes quantum dots having different diameters from each other as taught by Song et
`
`al. for the system of Kakinuma et al. in view of Chae et al. and Lee et al. since this would help to increase
`
`color purity and color reproducibility (Song et al., Abs, [0069]).
`
`Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Kakinuma et al. in view of
`
`Chae et al. and Lee et al. as applied to claim 1 above, and further in view of Ninan et al. (US
`
`2012/0154464).
`
`Regarding claim 8, Kakinuma et al. does not teach that a second display panel disposed
`
`between the first display panel and the color conversion unit, wherein the first display panel displays a
`
`color image and the second display panel displays a black-and-white image.
`
`Ninan et al. teaches that a second display panel (LCD achromatic in Fig. 8A, [0115-0117, 0156])
`
`disposed between the first display panel (LCD color in Fig. 8A, [0115-0117, 0156]) and the color
`
`

`

`Application/Control Number: 16/168,394

`
`Page 11
`
`conversion unit (the unit of QD’s in Fig. 8A), wherein the first display panel (LCD color in Fig. 8A, [0115-
`
`0117, 0156]) displays a color image (Fig. 8A, [0115-0117, 0156]) and the second display panel (LCD
`
`achromatic in Fig. 8A, [0115-0117, 0156]) displays a black-and-white image ([0116, 0156])
`
`Before the effective filling date of the claimed invention, it would have been obvious to the
`
`artisan of ordinary skill to employ that a second display panel disposed between the first display panel
`
`and the color conversion unit, wherein the first display panel displays a color image and the second
`
`display panel displays a black-and-white image as taught by Ninan et al. for the system of Kakinuma et
`
`al. in view of Chae et al. and Lee et al. since this would help that dual modulation of light output levels
`
`with two LCD panels may be realized with constant light, it helps to illuminate different portion of image
`
`with different intensities/strengths of light based on image data (Ninan et al., [0117]).
`
`Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Kakinuma et al. in view of
`
`Chae et al., Lee et al. and Ninan et al. as applied to claim 8 above, and further in view of Nakai et al.
`
`(US 2009/0147186).
`
`Regarding claim 9, Kakinuma et al. also teaches that the first display panel (the front panel, 340
`
`and the real panel in Fig. 9) is an IPS type liquid crystal display panel ([0032, 0053, 0171]). Kakinuma et
`
`al. does not teach that the second display panel is an IPS type liquid crystal display panel.
`
`Nakai et al. teaches that (Fig. 37 and 39-41, [0194]) that the first display panel and the second
`
`display panel are an IPS type liquid crystal display panel ([0194]).
`
`Before the effective filling date of the claimed invention, it would have been obvious to the
`
`artisan of ordinary skill to employ that that the first display panel and the second display panel are an
`
`IPS type liquid crystal display panel as taught by Nakai et al. for the system of Kakinuma et al. in view of
`
`Chae et al., Lee et al. and Ninan et al. since this would be an obvious design choice to provide a IPS LCD
`

`
`display sufficiently effective operating in normally black mode and enabling the output of high contrast,
`
`super high quality video free from moire patterns (Nakai et al., [0194, 0452]).

`
`Ueki et al. (US 2015/0042933, Fig. 10) teaches that a width of the black matrix (20 in Fig. 10,
`
`[0042]) disposed at the boundary between the first color filter and the second color filter
`
`([0042]) is greater than a width of the light shielding unit (13 in Fig. 10, [0042-0043, 0076])
`
`disposed at the boundary between the first color conversion layer and the second color
`
`conversion layer ([0043]).
