Abstract: An adhesive film has an average slope of about −9.9 to about 0, as measured over a temperature range of about −20° C. to about 80° C. in a graph depicting a temperature-dependent storage modulus distribution of the adhesive film where the x-axis represents temperature (° C.) and the y-axis represents storage modulus (kPa). The adhesive film also has a storage modulus at about 80° C. of about 10 kPa to about 1,000 kPa.

Abstract: An adhesive composition for polarizing plates includes a (meth)acrylic copolymer prepared by copolymerization of a monomer mixture and a curing agent. The monomer mixture includes a hydroxyl group-containing (meth)acrylic monomer, a tertiary amine group-containing (meth)acrylic monomer and a monomer having a glass transition temperature (Tg) of about 100° C. or greater. The adhesive composition has a gel fraction of about 50% or greater after aging for 12 hours. An adhesive film is formed from the adhesive composition. An optical display includes the adhesive film.
