发明名称 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 mum to 180 mum and contains no retardation increasing agent. Retardation values Re and Rth of the cellulose acylate film meet the following formulae (III) to (V): <?in-line-formulae description="In-line Formulae" end="lead"?>46<=Re<=100 (III) <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Rth=a-5.9Re (IV) <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>520<=a<=670 (V) <?in-line-formulae description="In-line Formulae" end="tail"?> A polarizing plate and a VA mode liquid crystal display having wide viewing angle characteristics and small changes in color, which are using the cellulose acylate film, are provided.
