Optical Compensation Sheet, Process for Producing the Same, and Polarizing Plate and Liquid Crystal Display Device Using the Same |
摘要 |
A novel optical compensation sheet is disclosed. The sheet comprising a polymer layer formed by coating and drying a solution comprising a polymer compound and a solvent composition comprising 20% by weight or more of water; and an optically anisotropic layer formed on the surface of the polymer layer by hardening a liquid crystal layer comprising at least one liquid-crystalline compound under irradiation of ionizing radiation at a film surface temperature from 70 to 160° C.; wherein a frontal retardation (Re) value of the optically anisotropic layer is not zero, and the optically anisotropic layer gives substantially equal retardation values for light of a wavelength lambda nm coming respectively in a direction rotated by +40° and in a direction rotated by -40° with respect to a normal direction of a layer plane using an in-plane slow axis as a tilt axis (a rotation axis).
