Abstract: An optical film having a high Re and a low |Rth| is provided. An optical film consists of a composition that includes cellulose acylate having an acyl group including an aromatic group, and satisfies Formula (I) 150 nm≦Re (550)≦350 nm, Formula (II) −50 nm≦Rth (550)≦50 nm, and Formula (III) 0.07 nm≦degree of cross-sectional orientation P2z≦1, Here, Re (550) represents the in-plane retardation at a wavelength of 550 nm, and Rth (550) represents the thickness direction retardation at a wavelength of 550 nm.
