An optical film capable of uniform polarization conversion in a wide wavelength range as a polymerizable compound used to obtain an optical film such as a polarizing plate or a retardation plate as a member of a flat panel display (FPD). Provide new compounds to give. [Solution] The following compounds, etc. In the above formula, benzothiophene may be substituted with benzofuran, benzothiazole, or benzoxazole. In the above formula, S in benzothiazole may be substituted with —O—, —S—, —CO— or —N (R 2b ) —. R 2b represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms. The side chain moiety may be substituted with other substituents within a specific range. [Selection figure] None |
