Optical components and image display devices with adhesive sheets and adhesive layers

Abstract

This invention provides an adhesive sheet that reduces noise and exhibits excellent reliability at high temperatures. The adhesive sheet 1 comprises an adhesive layer 10 containing an acrylic polymer. The acrylic polymer has structural units derived from alkyl (meth)acrylate (A) having 4 to 12 carbon atoms, and structural units derived from alkyl (meth)acrylate (B) having 13 to 25 carbon atoms. The mass ratio of alkyl (meth)acrylate (A) to alkyl (meth)acrylate (B) [(alkyl (meth)acrylate (B) / (alkyl (meth)acrylate (A))] is 0.7 to 1.5. The adhesive sheet 1 is used in optical components.
