RETARDATION FILM, POLARIZING PLATE USING SAME, AND LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
<p>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, R1-R8 each represents a substituted or unsubstituted alkylcarbonyl group or a substituted or unsubstituted allylcarbonyl group, and R1-R8 may be the same as or different from one another.)</p> |
