MANUFACTURING FILM OF THERMOPLASTIC RESIN FILM

摘要

PROBLEM TO BE SOLVED: To manufacture a thermoplastic resin film capable of suppressing the occurrence of color irregularity after the elapse of time under a high temperature and high humidity condition when the film is incorporated in a liquid crystal display element. SOLUTION: The thermoplastic resin film is heat-treated at a temperature of the glass transition temperature from Tg-30°C to Tg+20°C of a thermoplastic resin for a time of 10-600 sec while fed under a tension of 2-120 N/cm2.
