OPTICAL COMPENSATION SHEET, METHOD FOR PRODUCING THE SAME, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY

摘要

An optical compensation sheet comprising a polymer layer formed by coating a transparent support with a solution composed of a solvent composition containing 20% or more of water and an optically anisotropic layer formed of a liquid crystal composition containing at least one kind of liquid crystal compound on the polymer layer. The optically anisotropic layer has a non-zero front retardation (Re), a retardation value measured by causing light of a wavelength of ? nm to enter from a direction inclining by +40°to the normal to the optical compensation sheet while making the in-plane slow axis the inclination axis (rotation axis) is substantially equal to the retardation value measured by causing light of a wavelength of ? nm to enter from a direction inclining by -40°to the normal to the optical compensation sheet while making the in-plane slow axis the inclination axis (rotation axis). The polymer layer and the optically anisotropic layer are bonded chemically.
