Document Type and Number:
WIPO Patent Application WO/2023/238761
Kind Code:
A1
Abstract:
Provided is an optical laminate in which adhesive staining is suppressed and that includes two or more optically functional layers that each have a non-optically functional part, the non-optically functional parts being precisely aligned. An optical laminate according to an embodiment of the present invention has a first optically functional layer including an adhesive layer, and a second optically functional layer that is layered on the first optically functional layer via the adhesive layer. The first optically functional layer has a first non-optically functional part, and the second optically functional layer has a second non-optically functional part. The first non-optically functional part and the second non-optically functional part have a similar shape in plan view, and the centers of the first non-optically functional part and the second non-optically functional part are aligned. The first non-optically functional part and the second non-optically functional part are each formed as portions of respective films that constitute the first optically functional layer and the second optically functional layer.
