Abstract:
1. A method for manufacturing an optical device comprising a polarizing plate, wherein the polarizing plate comprises: a polyvinyl alcohol- or polyvinylene-base polarizing film; and a protective film laminated on at least one side of the polarizing film, wherein the protective film is composed of a triacetyl cellulose, a polycarbonate, a polyethylene terephthalate, a polyethylene naphthalate, a (meth)acrylate resin, an alicyclic polyolefin resin or an alicyclic acrylic resin, wherein said method comprises: treating at least one surface of the surfaces of the polarizing film and the protective film that are in contact with each other, with energy rays having an energy of at least 5 eV; and then directly laminating the polarizing film and the protective film on top of one another without any adhesive layer including a pressure sensitive adhesive layer interposed therebetween.
