A novel optically anisotropic film useful for optical compensation of a liquid crystal display device is provided. The optically anisotropic film has a distorted twisted spiral structure, which is formed from a liquid-crystalline composition comprising a liquid-crystalline compound and at least one optically active compound the torsional force of which is changed by light. The optically anisotropic film is produced, for example by (1) heating a liquid-crystalline composition to temperature T1; and (2) irradiating the liquid-crystalline composition with polarized light at temperature T2, provided TNI
