COMPOSITE POLARIZING PLATE, ITS MANUFACTURING METHOD, COMPOSITE OPTICAL MEMBER AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a composite polarizing plate made thinner than the conventional composite polarizing plate while keeping the optical performance equal to that of the conventional composite polarizing plate, a method for manufacturing the composite polarizing plate, and a composite optical member and a liquid crystal display device in each of which the composite polarizing plate is used.

SOLUTION: The composite polarizing plate 10 is constituted so that a transparent protective film 12 is stuck to one surface of a polarizer 11 and a transparent resin film 13, a primer layer 14 and a coating retardation layer 15 containing an organically-modified clay complex and a binder resin are formed in this order on the other surface of the polarizer. The method for manufacturing the composite polarizing plate comprises the steps of: forming the primer layer 14 on the surface of the transparent resin film 13; forming the coating retardation layer 15 on the surface of the primer layer 14; and sticking the transparent protective film 12 and the transparent resin film 13-located side of the coating retardation layer-formed transparent resin film 13 respectively to one surface of the polarizer 11 and the other surface of the polarizer by using an adhesive.
