Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Regarding claim 10, Chen in Fig. 10 further teaches a bank layer 134 (¶ 25, first shielding portion 134), wherein the bank layer comprises a first opening (Fig. 10, ¶ 39, the opening between two sections of the first shielding portion 134 corresponding to the rightmost light-emitting unit 100, since a display device includes green sub-pixels, red sub-pixels and blue sub-pixels, each of the sub-pixels correspond to a light-emitting unit 100), and the scattering element 144 is disposed in the first opening (Fig. 10).
Regarding claim 11, Chen in Fig. 10 further teaches the bank layer 134 comprises a second opening (Fig. 10, the opening between two sections of the first shielding portion 134 corresponding to the light-emitting unit 100 in the middle), and the color conversion element 13R is disposed in the second opening (Fig. 10).
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 7-8 are rejected under 35 U.S.C. 103 as being unpatentable over Chen in view of US 2017/0076678 A1 to Lee et al. (“Lee”).
Regarding claim 7, Chen in Fig. 10 teaches a first color filter layer 146 (¶ 35, filter layer 146 is a filter layer used for blue light i.e., color filter layer), wherein a portion of the first color filter layer 146 is the first color filter element 146 of the first optical structure 144, 146; and
a second color filter layer 142 (¶ 34, filtering portion 142 blocking blue light), wherein a portion of the second color filter layer 142 is the second color filter element 142 of the second optical structure 130R, 142.
Chen further discloses the optical structures 144, 146, 130R, 142 are parts of a light conversion layer 108 (Fig. 10, ¶ 20).
Chen does not explicitly disclose another portion of the first color filter layer and another portion of the second color filter layer are stacked to form a light blocking structure.
Lee recognizes a need for preventing color mixing in a display device (¶ 3, ¶ 49). Lee satisfies the need by providing a first color filter layer 320B, 320B’ (Fig. 1, ¶ 48, a collective of blue color filters 320B and 320B’), wherein a portion of the first color filter layer 320B is a first color filter element 320B (Fig. 1, ¶ 48, ¶ 74, blue color filter 320B overlaps the color conversion layer 330B); and
a second color filter layer 320R, 320R’ (Fig. 1, ¶ 48, a collective of red color filters 320R and 320R’), wherein a portion of the second color filter layer 320R is a second color filter element 320R (Fig. 1, ¶ 48, ¶ 74, red color filter 320R overlaps the color conversion layer 330R),
wherein another portion 320B’ (Fig. 1) of the first color filter layer 320B, 320B’ and another portion 320R’ (Fig. 1) of the second color filter layer 320R, 320R’ are stacked to form a light blocking structure 320 (Fig. 1, ¶ 50, partition 320 formed by overlapping the color filters 320R and 320B’ is a light blocking region SA).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify light conversion layer taught by Chen with the structure of the first and second color filter layers taught by Lee, so as to prevent color mixing in a display device (Lee: ¶ 3, ¶ 49).
Regarding claim 8, the combination of Chen and Lee further teaches an orthographic projection of the light blocking structure 320 (Lee: Fig. 1; Chen: Fig. 10. Lee’s structure 320 would replace the Chen’s first shielding portion 134 (Chen: ¶ 25)) on (i.e., in proximity to) the second substrate 102 (Chen: Fig. 10) is disposed between the orthographic projection of the first light emitting diode 100 (Chen) on the second substrate 102 and the orthographic projection of the second light emitting diode 100 (Chen) on the second substrate 102.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
US 2018/0182814 A1 to Kim et al. relates to display including a plurality of pixels having a first pixel, a second pixel and a third pixel, in which a first color filter overlapping the first and second pixels, a second color filter overlapping the first and third pixels, and a third color filter overlapping the second and third pixels.
