发明名称 Liquid crystal display device with improved viewing angle dependence of color
摘要 The present invention discloses a liquid crystal display device with improved viewing angle dependency upon contrast and color, comprising a liquid crystal cell having a pair of substrates each equipped with transparent electrodes and a liquid crystal layer positioned therebetween, polarizers disposed on opposite sides of the cell and a compensation plate disposed between at least one of the polarizers and the cell, in which at least one layer of the compensation plate is an aligned film comprising a liquid crystalline polymer or a polymer having a specific molecular structure, and a refractive index in a direction perpendicular to a plane of the film is larger than the minimum refractive index in a direction parallel to the plane.
