摘要：
An adhesive film for polarizing plates, a polarizing plate including the same, and an optical display including the same are provided. The adhesive film for polarizing plates is formed of an adhesive composition comprising: a (meth)acrylic copolymer; an adhesion promoter; a mixture of an isocyanate curing agent and a carbodiimide curing agent; and a UV absorbent, and the adhesive film has a glass transition temperature of about −47° C. to −40° C., and the adhesive film has a light transmittance of about 3% or less at a wavelength of about 380 nm.
