OPTICAL FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY USING THE SAME

摘要

An optical film, containing a cellulose acylate, and at least one compound represented by any of formulas (I) to (III):;wherein, in formulas (I) to (III), R1 and R2 each independently represent a halogen atom, an alkyl, cycloalkyl, alkenyl, aryl, hydroxy, hydroxyamino, amino, alkylamino, arylamino, alkoxy, aryloxy, alkylthio, or arylthio group (however, R1 and R2 do not represent an amino, alkylamino, or arylamino group at the same time); R3 to R6 each independently represent a hydrogen atom, an alkyl, cycloalkyl, alkenyl, aryl, acyl, alkyl- or aryl-sulfonyl, alkyl- or aryl-sulfinyl, carbamoyl, sulfamoyl, alkoxycarbonyl, or aryloxycarbonyl group; R7 represents an alkyl, cycloalkyl, alkenyl, aryl, alkylamino, arylamino, alkoxy, aryloxy, or heterocyclic group; R8 represents an alkyl, cycloalkyl, alkenyl, aryl, or heterocyclic group; and R1 to R8 each may be further substituted with a substituent; and a polarizing plate and a liquid crystal display.
