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.
