CELLULOSE ESTER FILM AND METHOD FOR PRODUCING THE SAME, POLARIZING PLATE, OPTICAL COMPENSATION FILM, ANTIREFLECTION FILM, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method mild to the environment and for producing a cellulose ester film having improved image unevenness and change of visibility with time on a display screen, caused when being incorporated in a liquid crystal display device.

SOLUTION: The cellulose ester film having 20-300 μm thickness is formed by melting a mixture comprising 100 pts.mass of a cellulose ester having a specified substitution degree, and 0.02-3 mass% of a stabilizer having a hydroxyphenyl group and a phosphite ester group, and ≥500 molecular weight at 180-240°C and extruding the melted product from a die.
