LIQUID CRYSTAL DISPLAY UNIT

摘要

A liquid crystal display unit, especially a liquid crystal display unit using an OCB (Optically Compensated Bend) technology capable of realizing a wide viewing angle and a fast response. An optically compensated element (40A)(40B) is provided with a first phase difference plate (42A)(42B) and a second phase difference plate (44A)(44B) having thickness-direction retardation. When a value obtained by normalizing a retardation amount Deltan.d for a light with each wavelength by a retardation amount Deltanlambda .d for a light with a specified wavelength lambda is Delta n/Deltanlambda, a value Deltan/Deltanlambda normalized at the first phase difference plate (42A)(42B) for lights with wavelengths other than a specified wavelength is characterized by being smaller than a value Deltan/Deltanlambda normalized at a liquid crystal layer, and a value Deltan/Deltan lambda normalized at the second phase difference plate (44A)(44B) is characterized by being larger than a value Deltan/Deltanlambda normalized at a liquid crystal layer.
