Abstract:
An adhesive film for polarizing plates, a polarizing plate including the same, and an optical display including the same are provided. An adhesive film for polarizing plates is formed of an adhesive composition including a (meth)acrylic copolymer and a cellulose ester binder. The (meth)acrylic copolymer contains an alkyl group, a hydroxyl group, an alicyclic group, and a hetero-alicyclic group. The adhesive film has a modulus at 30° C. of about 100,000 Pa or more.
