PROBLEM TO BE SOLVED: To provide an optical anisotropic film useful for optical compensation of a liquid crystal display device. SOLUTION: A biaxial optical anisotropic film having a twisted spiral structure is formed by emitting polarization to a composition containing at least one polymerizable liquid crystal compound and at least one optically active compound which may be racemized by light. The optically active compound is expressed by general formula (3), for example (L<SP>4</SP>expresses a 3C or higher divalent linking group, Q expresses a polymerizable group, and L<SP>5</SP>expresses a bivalent linking group).
