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.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

Claim Rejections - 35 USC § 103
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 (i.e., changing from AIA to pre-AIA ) 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.
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, 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.
Claim(s) 2, 5 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Nakamura in view of Hatano et al. (US Pub. No. 2012/0217516 A1), hereafter referred to as Hatano.
As to claim 2, Nakamura discloses the display device of claim 1 (paragraphs above).
Nakamura does not disclose a second sealing layer which is formed of an inorganic material and covers the first resin layer,
wherein the color filter is provided on the second sealing layer.
Nonetheless, Hatano discloses a similar display device (figs 1A-B) comprising a second sealing layer (fig 1B, 168) which is formed of an inorganic material ([0103]) and covers a first resin layer ([0103]),
wherein a color filter (166; [0043]) is provided on the second sealing layer (168).
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to include the second sealing layer of Hatano in the display device of Nakamura since this will prevent diffusion of an impurity component and the like contained in the color filter to the light-emitting layer.
As to claim 5, Nakamura in view of Hatano disclose the display device of claim 2 (paragraphs above).
Nakamura does not disclose a second resin layer which covers the color filter.
Nonetheless, Hatano further discloses a second resin layer (fig 1B, 163; [0122], [0119]) which covers the color filter (166).
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to form the color filter on the sealing layers with the second resin layer between the color filter and second substrate as taught by Hatano in the display device of Nakamura since this prevent moisture and contaminates from reaching the organic emission layer.
As to claim 17, Nakamura discloses the display device of claim 16 (paragraphs above),
Nakamura does not disclose wherein a width of the light-shielding layer is greater than a width of the partition.
Nonetheless, Hatano further discloses wherein a width of a light-shielding layer (164) is greater than a width of a partition (126).
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to form the width of the light-shielding layer greater than that of the width of the partition in the display of Nakamura as taught by Hatano since this will decrease light leakage between sub-pixels.
Claim(s) 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Nakamura in view of Zhou et al. (US Pub. No. 2025/0268045 A1), hereafter referred to as Zhou.
As to claim 10, Nakamura discloses the display device of claim 9 (paragraphs above).
Nakamura further discloses a conductive layer (145) connected to the partition (160); and
wherein the light-shielding layer (220) faces a contact portion (contact of 145 and 160).
Nakamura does not disclose a conductive layer provided in a surrounding area around a display area including the display element;
a feed line provided in the surrounding area; and
a contact portion which connects the feed line and the conductive layer to each other.
Nonetheless, Zhou discloses a conductive layer provided in a surrounding area around a display area including a display element (fig 3, power supply layer 310 in surrounding area 300 and display area 100 with display element 24; [0118]);
a feed line (330) provided in the surrounding area (300); and
a contact portion which connects the feed line and the conductive layer to each other (contact between 330 and 310).
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to include the conductive layer and feed line in the surrounding portion of a display device as taught by Zhou in the surrounding area of the display of Nakamura since this will allow for a low resistance power connection which decreases voltage drop across the display device.
Claim(s) 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Nakamura in view of Du et al. (US Pub. No. 2022/0399423 A1), hereafter referred to as Du.
As to claim 15, Nakamura discloses the display device of claim 14 (paragraphs above),
Nakamura does not disclose wherein the rib comprises a first pixel aperture which overlaps the first display element, a second pixel aperture which overlaps the second display element and a third pixel aperture which overlaps the third display element (fig 3A, 143 with apertures for red, green and blue sub-pixels).
Nakamura does not disclose sizes of the first pixel aperture, the second pixel aperture and the third pixel aperture are different from each other.
Nonetheless, Du discloses wherein sizes of a first pixel aperture, a second pixel aperture and the third pixel aperture are different from each other (fig 1 and [0048]-[0050]).
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to form the pixel apertures of Nakamura with different sizes as taught by Du since this will balance the light-emitting brightness of sub-pixels of different colors with different light emitting efficiencies.
Claim(s) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Nakamura in view of Hatano and further in view of Ochi et al. (US Pub. No. 2019/0363275 A1), hereafter referred to as Ochi.
As to claim 3, Nakamura in view of Hatano disclose the display device of claim 2 (paragraphs above).
Nakamura in view of Hatano do not disclose a dam structure provided in a surrounding area around a display area including the display element,
wherein the dam structure includes a plurality of protrusions, and
the second sealing layer covers at least part of the protrusions.
Nonetheless, Ochi discloses a dam structure (fig 1, DM) provided in a surrounding area around a display area including a display element (DA 5 with display elements 4),
wherein the dam structure includes a plurality of protrusions (DM), and
a second sealing layer (33) covers at least part of the protrusions (DM).
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to include the dam structure of Ochi in the display device of Nakamura in view of Hatano since this will inhibit the infiltration of moisture into the TFT and organic emission layers by blocking a path of permeation of the moisture and thus allowing the reliability of the display to be improved.
