Optical film |
| abstract |
Provided is an optical film which exhibits low internal haze, low internal scattering, and excellent moisture resistance though the film contains diacetylcellulose having excellent retardation-inducing properties. An optical film characterized by comprising: a cellulose acetate α which has a 6% viscosity of 70 to 250 mPas and a degree of acetyl substitution of 2.0 to less than 2.5; another cellulose acetate β which has a 6% viscosity lower than that of the cellulose acetate α and a degree of acetyl substitution of 2.0 to less than 2.5; ester compound C which has 1 to 12 pyranose or furanose structures of at least one kind and in which all or a part of the OH groups of the structures are esterified; and polyester D represented by Formula (1). B-(G-A)n-G-B (1). |
