THERMOPLASTIC RESIN FILM, PHASE DIFFERENCE FILM AND POLARIZER-PROTECTING FILM

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin film capable of protecting a liquid crystal and a polarizer from deterioration by ultraviolet light when used as a polarizer-protecting film and not causing defect of appearance by evaporation of ultraviolet light, a phase difference film and a polarizer-protecting film. SOLUTION: The thermoplastic resin film comprises 0.1-6 wt.% compound having ultraviolet light-absorbing group and has <5% light transmittance in 380 nm wavelength. COPYRIGHT: (C)2007,JPO&INPIT
