Abstract

PURPOSE:To prevent curling by sticking releasing paper to a polarizing film, formed on a polarizing film base, with a tackiness agent interposed and further sticking a protective film to the other surface of the base with a tackiness agent and an adhesive interposed. CONSTITUTION:On the opposite surface of a polarizing film base 2 to the surface where a polarizing film is formed, a protective film 47 is stuck with a tackiness agent 11 and an adhesive 12 interposed; the tackiness agent 11 uses ethylene-vinyl acetate copolymer resin (EVA) free of the residing of an cohesion part and having low cohesive strength. The protective film 7 has high elasticity and is fixed to the tackiness agent 11 having low cohesive strength through the adhesive 12 having adhesive strength and the tackiness agent 1 is further fixed to the polarizing film base 2. Consequently, even if the polarizing film absorbs moisture and the polarizing plate is to curl, the adhesive 12 is adhered to the protective film and never moves, thereby preventing the curling of the plate 10 by the protective film 7.
