Abstract

Disclosed is a polarizing plate using a polyester film as a polarizer protective film, wherein there hardly occurs separation at the interface between the polarizer and the protective film. Specifically disclosed is a polarizing plate wherein at least one polyester film (E), at least one major surface of which is provided with a highly adhesive layer (H), and a polarizer (P) are laminated in such a manner that the surface of the polyester film on which the highly adhesive layer is formed faces the polarizer through an adhesive layer (G). The polarizer (P) and the polyester film (E) are preferably laminated through an adhesive layer which is composed of a resin solution containing a polyvinyl alcohol resin, a crosslinking agent and a metal compound colloid having an average particle diameter of 1-100 nm. The metal compound colloid is contained in the adhesive layer in an amount of not more than 200 parts by weight per 100 parts by weight of the polyvinyl alcohol resin.
