PROBLEM TO BE SOLVED: To provide a cellulose acylate film having good surface properties and very few foreign bodies, and capable of suppressing image unevenness on the display screen, generated when built in a display device, and visibility change due to moisture. SOLUTION: The cellulose acylate film is produced by melt-flowing a composition containing 0.01-3 mass% lactone-based compound represented by formula (II) based on cellulose acylate having a prescribed substitution degree (wherein, R<SP>1</SP>-R<SP>4</SP>are H, a 1-20C alkyl, a 7-20C aralkyl or a 6-15C aryl).
