CELLULOSE ACYLATE FILM, POLARIZING PLATE, RETARDATION 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 humidity and high temperature when incorporated to a liquid crystal display device.

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