Abstract: Provided are an adhesive composition for a polarizing plate, a polarizing plate, and an optical display device, the adhesive composition comprising an epoxy-based compound, a (meth)acrylate-based compound, a photo-acid generator, and an optical radical initiator, the (meth)acrylate-based compound comprising a mixture of a bifunctional (meth)acrylate-based compound and a monofunctional (meth)acrylate-based compound having a hydrophobic functional group, wherein the adhesive strength measured after the adhesive composition for a polarizing plate is separately applied to a PET film, a TAC film, and a COP film, to which a polarizer is then bound, followed by photo-curing, is about 200 gf/inch or more.
