ABSTRACT:
A cellulose acylate resin film which can suppress generation of color nonuniformity even after exposure to high temperature and high humidity when incorporated in a liquid crystal display element can be produced. The cellulose acylate resin film is heat-treated at a temperature of Tg−30° C. to Tg+20° C., Tg representing the glass transition temperature of the cellulose acylate resin, for 10 seconds to 600 seconds while conveying the cellulose acylate resin film at a tension of 2 N/cm2to 120 N/cm2.
