Disclosed is a cellulose ester optical film characterized by containing a cellulose ester, a polymer (a) defined below and a compound (b) defined below. (a) a polymer obtained by copolymerizing an ethylenically unsaturated monomer having a partial structure represented by the general formula (1) below in a molecule and at least one ethylenically unsaturated monomer (b) at least one compound selected from the group consisting of carbon radical scavengers, phenol compounds and phosphorus compounds. (In the formula, R
