<P>PROBLEM TO BE SOLVED: To provide an optical film and a polarizing plate which do not cause light leakage thereby cause no luminescent spot or no defect even if they are arranged between a polarizer and a liquid crystal cell, and black display is performed. <P>SOLUTION: The optical film is disclosed in which light-shielding processing is applied to an optical defect causing light leakage, the optical defect appearing when a thermoplastic resin film such as a thermoplastic saturated norbornene resin, a polycarbonate resin, a polysulfonic resin, a polyether sulfonic resin, and a polymethyl methacrylate resin is located between polarizers arranged at crossed Nicols, and the polarizing plate is disclosed on which the optical film and the polarizers are layered. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
