<P>PROBLEM TO BE SOLVED: To provide a polarizing plate having sufficient durability in a severe environment at high temperature and high humidity. <P>SOLUTION: The polarizing plate comprises a polarizer, an adhesive layer and a transparent protective film bonded to at least one side of the polarizer via the adhesive layer. The adhesive layer is formed of an active energy ray curing adhesive containing at least one curable component and the adhesive layer has a glass transition temperature (Tg) of 60°C or more and thickness of 0.01 to 7 μm. In the adhesive layer, a (meth)acryloyl group-containing compound, specifically an N-substituted amide monomer, may be use as a curable component. As the N-substituted amide monomer, at least one selected from N-hydroxyethylacrylamide, N-methylolacrylamide, N-isopropylacrylamide and N-acryloylmorpholine, is preferable. <P>COPYRIGHT: (C)2011,JPO&INPIT |
