OPTICAL FILM, METHOD FOR PRODUCING THE SAME, POLARIZER, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optical film which has little haze, achieves excellent lamination to a PVA polarizer, and reduces light leakage when assembled into a liquid crystal display device.

SOLUTION: An optical film comprises a core layer containing a thermoplastic resin, and an outer layer containing cellulose acylate which is arranged at least on one side of the core layer. The outer layer contains a photoelastic coefficient reducing agent.
