    Abstract: An optical film including cellulose acylate and a compound represented by General Formula (I) described below, a polarizing plate, and a liquid crystal display device; R1 and R3 represent hydrogen atoms, alkyl groups having 1 to 20 carbon atoms, cycloalkyl groups having 3 to 20 carbon atoms, alkenyl groups having 2 to 20 carbon atoms, or aromatic groups having 6 to 20 carbon atoms. R5 represents a hydrogen atom, an unsubstituted alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms, or an aralkyl group represented by -L5-Ar5 (L5 represents an alkylene group having 1 to 20 carbon atoms and Ar5 represents an aromatic group having 6 to 20 carbon atoms). Here, the total of ring structures present in R1, R3, and R5 is one or two.

    Abstract: A polarizing plate protective film contains a compound represented by general formula (II-1) or (II-2). In general formulas (II-1) and (II-2), X represents a 6-membered cyclic acetal group; n represents an integer of 2 or more; and a plurality of Xs may be identical or different. In general formula (II-1), Z2 represents a linking group having a valence of n; R1 represents a substituent, when there are a plurality of R1s, at least two of the plurality of R1s may be taken together to form a ring, R1s in different benzene rings may be taken together to form a single bond; m represents an integer of 0-4; and the plurality of R1s may be identical or different. In general formula (II-2), Z3 represents an alkylene group having a valence of n, provided that Z3 does not have a ring structure.
