ABSTRACT:
A novel optical compensation film is disclosed. The optical compensation film comprises a first optically anisotropic layer and a second optically anisotropic layer, each of which formed of a composition comprising a liquid-crystalline compound, wherein molecules of the liquid-crystalline compound in each of the first and second optically anisotropic layers are fixed in a hybrid alignment state in which tilt angles of the molecules with respect to a layer plane varies in a thickness direction.
