摘要:
A cellulose ester film containing a polyester represented by Formula (1) or (2), wherein an in-plane retardation value (Ro) is 0 to 5 nm and a retardation value in a thickness direction (Rt) is −20 to 10 nm, Ro and Rt being measured at 23° C. and 55% RH: B1-(G-A-)mG-B1 Formula (1) wherein B1: monocarboxylic acid, G: dihydric alcohol, A: dibasic acid, B1, G and A contain no aromatic ring, m: repeat number, plural B1 may be the same or different, and plural G may be the same or different; and B2-(A-G-)nA-B2 Formula (2) wherein B2: monoalcohol, G: dihydric alcohol, A: dibasic acid, provided that none of B2, G and A contains an aromatic ring, n: repeat number, plural B2 may be the same or different, and plural G may be the same or different.
