摘要： A liquid crystal display device includes an OCB mode liquid crystal display panel, and an optical compensation element which is disposed outside of the liquid crystal display layer. The optical compensation element includes a polarizer plate, a first retardation plate which is disposed between the polarizer plate and the liquid crystal layer, and a second retardation plate which is disposed between the polarizer plate and the first retardation plate and has a biaxial refractive index anisotropy. The optical compensation element compensates a difference of a polarization state that differs between azimuth directions of light passing through the liquid crystal layer and compensates a shift of the polarization state of light, which passes through the retardation plate, from an azimuth direction of an absorption axis of the polarizer plate.
