The present invention provides a cellulose acylate film which can improve the optical characteristics and durability of a polarizing plate and enhance the performance of a liquid crystal display device, and a polarizing plate and a liquid crystal display device using the cellulose acylate film. A cellulose acylate film containing cellulose acylate and at least one compound represented by the following general formula (I), a polarizing plate and a liquid crystal display device using the cellulose acylate film. R 1, R 3 and R 5 are a hydrogen atom, an alkyl group of C1-20, represents a C3~20 cycloalkyl group, alkenyl group or C 6 to 20 aromatic group of C2-20. However, any one of R 1 , R 3 and R 5 is an aralkyl group or a cycloalkyl group, and the total number of ring structures present in R 1 , R 3 and R 5 is 3 or more. [Selection figure] None |
