A cellulose mixed ester film is produced by melting a mixture of a cellulose mixed ester having a substitution degree of a certain range, fine particles having a mean primary particle size of from 0.005 μm to 2 μm and a UV absorbent in a certain ratio, extruding the mixture and forming the film through melt casting film formation. When the produced cellulose mixed ester film is built in a liquid crystal display device, display fluctuation and moisture-dependent visibility change are suppressed.
