摘要:
The polarizing plate of the invention comprises a norbornene resin film, a polyurethane layer, an adhesive layer and a polarizing film which are laminated in this order. The polarizing plate exhibits excellent adhesion between the optical film and the polarizing film, is excellent also in properties such as heat resistance and chemical resistance, rarely suffers delamination and distortion even if it is used for a long period of time, and has high reliability. The polarizing plate can be obtained by, for example, a process comprising steps of forming a polyurethane layer on a surface of a norbornene resin film and bonding a polarizing film to the polyurethane layer through an adhesive.
