CELLULOSE ACYLATE FILM, POLARIZING PLATE, PHASE DIFFERENCE FILM, OPTICAL COMPENSATION FILM, ANTIREFLECTION FILM, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a film capable of suppressing generation of color unevenness even under high temperature and high humidity when incorporated to a liquid crystal display device.

SOLUTION: A cellulose acylate film is characterized in that both wet heat dimensional variation (δL(w)) and dry heat dimensional variation (δL(d)) are 0 to 0.2%, both wet heat variation (δRe(w)) and dry heat variation (δRe(d)) of retardation in a plane (Re) are 0 to 10%, and both wet heat variation (δRth(w)) and dry heat variation (δRth(d)) of retardation in a thickness direction (Rth) are 0 to 10%.
