Optical compensating sheet having optically anisotropic layer made of discotic liquid-crystalline molecules and transparent substrate comprising polymer film

摘要

An optical compensatory sheet comprises a transparent support and an optically anisotropic layer. The optically anisotropic layer is made from discotic liquid crystal molecules. The transparent support is made of a polymer film. The polymer film has an Re retardation value in the range of 10 to 70 nm. The polymer film also has an Rth retardation value in the range of 70 to 400 nm. The polymer film further has a standard deviation of angle of slow axis of 1.5° or less.
