ester film having an acetyl group and a propionyl group is disclosed. Sum
of degree of acetyl substitution (DSac) and degree of propionyl
substitution (DSpr) of the fatty acid cellulose ester film of the film is
2.8 or less, and a retardation value (Rt value) in the thickness
direction define by Formula 1 is 60 to 300 nm.
