OPTICAL CELLULOSE ACYLATE FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY

摘要

A cellulose acylate film is provided and is excellent in increasability of an in-plane retardation and a retardation in a thickness direction, from which an additive does not bleed out, and which is excellent in surface properties. The cellulose acylate film has a thickness of 40 µm to 180 µm and contains no retardation increasing agent. Retardation values Re and Rth of the cellulose acylate film meet the following formulae (III) to (V): 46=Re=100 (III) Rth=a-5.9Re (IV) 520=a=670 (V) A polarizing plate and a VA mode liquid crystal display having wide viewing angle characteristics and small change in color, which are using the cellulose acylate film, are provided.
