Abstract
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)−5.9  (IV)520≦a≦670  (V) 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.
