Patent ID: 7929089

Claim:
An optical compensation film comprising, at least, first and second optically-anisotropic layers, wherein: retardation in plane at a wavelength of 550 nm, Re(550), of the first optically-anisotropic layer is from 20 to 40 nm, the first optically-anisotropic layer does not have any direction in which its retardation at a wavelength of 550 nm is 0 nm, the direction in which the absolute value of retardation of the first optically-anisotropic layer is the smallest is neither in the normal line direction of the layer nor in the in-plane direction thereof, and Re(550) of the second optically-anisotropic layer is from 20 to 150 nm and retardation along thickness direction at a wavelength of 550 nm, Rth(550), thereof is from 40 to 110 nm.
