Detailed Action
This office action is in response to applicant’s communication filed on 08/05/26. Claims 1-20 are pending in this application.
Claim Rejections Under 35 U.S.C. §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, 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 1-3, 6, 12, 13, 14 and 17 are rejected under 35 U.S.C. §103 as being unpatentable over Kwon (KR 20220093875 A) and further in view of Jung (US 20210249479 A1).

Regarding claim 13, Kwon and Jung disclose the display device of claim 1, wherein the second coating layer destructively interferes with specularly reflected light (Kwon discloses an interference pattern: The fine pattern can be configured in various ways, such as an elliptical pattern and a polygonal pattern, and by using a hologram pattern to refract the light incident by the interference pattern in an asymmetrical direction. Condensed light can be diffused at a more inclined angle.).
