Abstract

A optical compensation sheet comprises a transparent support, a polymer layer made by coating and drying onto the support a solution consisting of a solvent composition containing 20% ore more of water, and disposed thereon an optically anisotropic layer made from a liquid crystal composition containing at least one liquid crystal compound, wherein the front face retardation value (Re) of the optically anisotropic layer is not zero, a retardation value determined by inputting a light of λnm wavelength in the direction oblique at + 40 DEG to the normal direction of the optical compensation sheet which takes the in-plane slow axis as oblique axis (rotary axis) is substantially identical to that determined by inputting a light of λnm wavelength in the direction oblique at - 40 DEG to the normal direction of the optical compensation sheet which takes the in-plane slow axis as oblique axis (rotary axis), and the above polymer layer is chemically bonded to the above optically anisotropic layer. Moreover, an optical compensation sheet comprises a transparent support, a polymer layer on the support, and disposed on the surface of the polymer layer, an optically anisotropic layer made from a liquid crystal composition containing at least one liquid crystal compound and at least one fluorine-containing horizontal alignment agent, wherein the front face retardation value (Re) of the optically anisotropic layer is not zero, a retardation value determined by inputting a light of λnm wavelength in the direction oblique at + 40 DEG to the normal direction of the layer plane which takes the in-plane slow axis as oblique axis (rotary axis) is substantially identical to that determined by inputting a light of λnm wavelength in the direction oblique at -40 DEG to the normal direction of the layer plane which takes the in-plane slow axis as oblique axis (rotary axis).
