<P>PROBLEM TO BE SOLVED: To provide a new cellulose acylate film having a large absolute value of Re and a small absolute value of Rth. Ž<P>SOLUTION: The cellulose acylate film comprises a composition comprising at least one cellulose acylate having an aromatic group-containing acyl group (substituent A), in which a substitution degree of the substituent A satisfies following relational expressions (I) and (II): -0.25≤DSA2+DSA3-DSA6≤0.20 (I), 0.35≤DSA2+DSA3+DSA6 (II), wherein DSA2, DSA3 and DSA6 each indicates a substitution degree with the substituent A at the 2-, 3- and 6-positions of the cellulose acylate.
