ABSTRACT:
A novel optical compensation film is disclosed. The film comprises at least a first optically anisotropic layer and a second optically anisotropic layer, the first optically anisotropic layer having an in-plane retardation of 0 to 10 nm and an in-thickness direction retardation of −400 to −80 nm, the second optically anisotropic layer having an in-plane retardation of 20 to 150 nm and an in-thickness direction retardation of 100 to 300 nm, and at least either one of the first and second optically anisotropic layer being a polymer film.
