Document Type and Number:
WIPO Patent Application WO/2024/019162
Kind Code:
A1
Abstract:
The present invention provides an adhesive sheet that is capable of suppressing corrosion of a conductive layer, especially a conductive layer containing a metal oxide such as ITO, and is suitable for adjusting the anchoring force with an optical film to a large value. The adhesive sheet 1 of the present invention is formed from an adhesive agent composition containing a monomer group and/or a polymer of the monomer group. The adhesive sheet 1 has a first surface 1a and a second surface 1b that are opposite to each other. In the adhesive sheet 1, the amount of carboxyl group-containing monomers blended in the adhesive agent composition and the element ratio R1 in the first surface 1a satisfy at least one selected from the group consisting of requirements (1) and (2).
