Pressure-sensitive adhesive plates, optical components with pressure-sensitive adhesive layers, and image display devices.

Abstract

The invention relates to a pressure-sensitive adhesive sheet that allows for the reduction of interference and superior reliability at high temperatures. The pressure-sensitive adhesive sheet (1) comprises a pressure-sensitive adhesive layer (10) containing an acrylic polymer. The acrylic polymer has constituent units derived from (met)acrylic alkyl ester (A) with an alkyl group of 4 to 12 carbon atoms and constituent units derived from (met)acrylic alkyl ester (B) with an alkyl group of 13 to 25 carbon atoms. The mass ratio between (met)acrylic alkyl ester (A) and (met)acrylic alkyl ester (B) [(met)acrylic alkyl ester (B) / (met)acrylic alkyl ester (A)] is 0.7 to 1.5. The pressure-sensitive adhesive sheet (1) is used for optical components.
