Retardation film, polarizing plate using same, and liquid crystal display device |
| abstract |
The purpose of the present invention is to provide: a retardation film which uses a low-substituted cellulose ester and has improved retardation after saponification and improved wet heat stability of internal haze; a polarizing plate which uses the retardation film; and a liquid crystal display device. An optical film of the present invention contains a cellulose ester and a compound represented by general formula (1), and is characterized in that the compound has an average degree of substitution within the range of 3.0-6.0 and contains a component having a degree of substitution of 4 or less in an amount of 30-80% by mass (inclusive). (In the formula, R 1 -R 8 each represents a substituted or unsubstituted alkylcarbonyl group or a substituted or unsubstituted allylcarbonyl group, and R 1 -R 8 may be the same as or different from one another.) |
