发明名称 Liquid crystal display
摘要 A liquid crystal display of a vertical alignment (VA) mode using a circular polarization plate is provided which can reduce light leak as observed along an oblique direction and achieve a high contrast ratio. The VA mode uses a liquid crystal layer of vertical alignment in an initial alignment state. A film having generally isotropic optical characteristics in an omnidirection is used as a protective film, on a liquid crystal cell side, of first and second polarization plates disposed outside the liquid crystal cell, and first and fourth retardation films have an Nz coefficient smaller than 1.
