Abstract: An optical film is provided containing cellulose acylate and at least one type of a compound denoted by the following Formula (I). R1 represents a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, a heterocyclic group, an acyl group, an alkoxy carbonyl group, a carbamoyl group, an alkyl sulfonyl group, or an aryl sulfonyl group, R2 represents an alkyl group or an aryl group, L represents a single bond or a bivalent or more connecting group, and n represents 1 when L is a single bond and n represents an integer of the valence of L−1 when L is a bivalent or more connecting group. s and t each independently represent 1 to 3, and X represents —O— or —N(Ra)-. Ra represents a hydrogen atom or an alkyl group.
