Abstract: Disclosed is an optical film having a cellulose ester and a polyester containing an alicyclic structure and having a hydroxyl terminal group, a hydrogen atom of which is substituted by an acyl group derived from a monocarboxylic acid, and having a thickness of from 10 to 45 μm, an in-plane retardation of from −5 to 5 nm, a retardation in thickness direction of from −5 to 5 nm, and an elastic modulus of 4.2 GPa or more. The optical film has a reduced thickness, achieves both a high rigidity and optical characteristics including a low retardation, and enhances the polarizer durability used in a polarizing plate.
