| Zusammenfassung: | The present invention relates to an optically anisotropic cellulose ester film. The invention also relates to an optical compensatory sheet, an ellipsoidal polarizing plate and a liquid crystal display.
An optically anisotropic cellulose ester film is disclosed. The film contains a discotic compound in an amount of 0.01 to 20 weight parts based on 100 weight parts of cellulose ester. The film has a Rthretardation value in the range of 60 to 1,000 nm. The cellulose ester film can be used in an optical compensatory sheet, an ellipsoidal polarizing plate and a liquid crystal display. |
