<P>PROBLEM TO BE SOLVED: To provide a polarizing plate allowed to be manufactured in a short time by a simple manufacturing process and excellent in chip cut resistance, humidity/heat resistance, an adhesive property between a protection film and a polarizer, and so on. <P>SOLUTION: The polarizing plate 1 is constituted by laminating protection films 5, 6 composed of cyclic olefin resin films on both the sides of a polyvinyl alcohol polarizing film 2 through adhesive layers 3, 4. Each of the adhesive layers 3, 4 is composed of a cure object of a radiation curing composition containing an alicyclic epoxy compound (A), a compound (B) expressed by a formula: HO-(R<SP>1</SP>-O-CO-O)<SB>m</SB>-(R<SP>2</SP>-O-CO-O)<SB>n</SB>-R<SP>3</SP>-OH whose number average molecular weight is ≥500, and a photoacid generator (C). (In the formula, R<SP>1</SP>and R<SP>2</SP>respectively independently express a divalent hydrocarbon radical of carbon number 2-12, R<SP>3</SP>expresses the same structure as either one of the R<SP>1</SP>and the R<SP>2</SP>, m is 2-150, n is 0-150, and m + n is 2-200). <P>COPYRIGHT: (C)2008,JPO&INPIT |
