Election/Restrictions Applicant’s election without traverse of Species A in the reply filed on 2/27/2026 is acknowledged. Claim 20 is withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected species, there being no allowable generic or linking claim.

Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b ) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the appl icant regards as his invention. Claims 1-19 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 1, the limitation “a first insulating layer, a second insulating layer, a third insulating layer and a fourth insulating layer that are sequentially stacked on the first surface of the substrate and respectively include an opening exposing the first surface of the substrate in the emission area” is unclear to the examiner because the first-fourth insulating layers are formed in the non-emission areas and the openings are formed in the emission area. Examiner requests applicant to clarify the first/second/third/fourth insulating layers are sequentially stacked in the non-emission areas and respectively include an openings exposing the first surface of the substrate in the emission area. Note: The dependent claims necessarily inherit the indefiniteness of the claims on which they depend. Regarding claim 19, the limitation “a first insulating layer, a second insulating layer, a third insulating layer and a fourth insulating layer that are sequentially stacked on the first surface of the substrate and respectively include an opening exposing the first surface of the substrate in the emission area” is unclear to the examiner because the first-fourth insulating layers are formed in the non-emission areas and the openings are formed in the emission area. Examiner requests applicant to clarify the first/second/third/fourth insulating layers are sequentially stacked in the non-emission areas and respectively include an openings exposing the first surface of the substrate in the emission area.
