Abstract

The present invention relates to a polarizing plate and an image display device having the same. More specifically, the present invention relates to a polarizing plate and an image display device having the same, the polarizing plate comprising: a polarizer layer; an adhesive layer formed on at least one surface of the polarizer layer; and a phase difference film including a structure in which a liquid crystal layer, an alignment layer, and a substrate make contact in regular sequence, and the liquid crystal makes contact with the adhesive layer, wherein the alignment layer is formed by a composition for forming the alignment layer, which includes an adhesion-reinforcing agent including an isocyanate group and a (meth)acrylate group at an end portion thereof so as to form bonds with a reactive group of the surface of the substrate and a reactive group in the liquid crystal compound of the liquid crystal layer, respectively, thereby simplifying a manufacturing process, achieving excellent interlayer adhesion, and enabling the implementation of a thin polarizing plate.
