Patent ID: 8652590

Claim:
A polarizing plate comprising: an acrylic film (a) having a moisture permeability of 100-500 g/m 2 ·24 hr; a cellulose ester film (b1) containing no phosphate plasticizer or a cellulose ester film (b2) containing a phosphate plasticizer and an acid scavenger; and a polarizer comprising a polyvinyl alcohol, the polarizer being sandwiched between the acrylic film (a) and one of the cellulose ester film (b1) and the cellulose ester film (b2), wherein the polarizing plate is provided on at least one surface of a liquid crystal cell so that cellulose ester film (b1) or (b2) faces the liquid crystal cell, wherein the acrylic film (a) comprises an acrylic resin (A) and a cellulose ester resin (B) at a weight ratio of 95:5 to 60:40 in a compatible state, wherein the acrylic resin (A) has a weight average molecular weight Mw of 80000 to 1000000, and the cellulose ester resin (B) has a weight average molecular weight Mw of 75000-300000 and a total substitution degree (T) of an acyl group of 2.0-3.0, wherein the acrylic film (a) is free from ductile fracture under a condition of 23° C. and 55% RH, and wherein the acrylic film (a) exhibits a tension softening point of 105-145° C. and a haze of less than 1%.
