PROBLEM TO BE SOLVED: To increase adhesion and various kinds of durability, to simplify the structure and to manufacture at a low cost with excellent productivity by forming a adhesive layer, composed of a specific thermosetting adhesive, to a substrate on one surface of a polarizing film. SOLUTION: This polarizing plate is manufactured by forming the adhesive layer 4, which is composed of the thermosetting adhesive consisting essentially of an ionomer resin produced by bonding the molecules of an ethylene- methacrylic acid copolymer with each other by a metallic ion and is stuck directly to the liquid crystal cell surface substrate, on one surface of the polarizing film 1 (the surface of the side bonded to the liquid crystal surface substrate). In such a case, the thermosetting adhesive consists essentially of the ionomer resin produced by bonding the molecules of the ethylene-methacarylic acid copolymer with each other by the metallic ion and the content of the methacrylic acid in the ethylene-methacrylic acid copolymer is 1-30wt.%, further preferably 14-45wt.%. And an organic peroxide is added to cure. |
