Liquid crystal display device |
摘要 |
A liquid crystal display device includes a liquid crystal display panel to which an OCB mode is applied, and an optical compensation element which optically compensates a retardation of the liquid crystal layer in a predetermined display state in which a voltage is applied to the liquid crystal layer. The optical compensation element includes a polarizer, a first retardation plate which is disposed between the polarizer and the liquid crystal display panel and in which discotic liquid crystal molecules are fixed in a state in which the discotic liquid crystal molecules are hybrid-aligned along a normal direction, and a second retardation plate which is disposed between the polarizer and the first retardation plate and has wavelength dispersion characteristics which are opposite to wavelength dispersion characteristics of an in-plane retardation in the liquid crystal layer.
