Liquid crystal display device

Abstract

A liquid crystal display device capable of ensuring a good contrast ratio and preventing a lowering in color reproducibility at the time of motion picture image display includes a liquid crystal layer 56, showing optically uniaxial alignment, disposed between a first substrate B provided with at least a transparent electrode 54 and a second substrate A provided with an electrode 58 having a reflection function; a phase plate 52 disposed on the first substrate B; and a polarizer 51 disposed on the phase plate 52. The polarizer 51 and the phase plate 52 are disposed so that an optical axis of the polarizer 51 and a slow axis of the phase plate 52 form an angle θ, and the polarizer 51 and the liquid crystal layer 56 are disposed so that the optical axis of the polarizer 51 and an optical axis of the liquid crystal layer 56 form an angle of 2θ+45 degrees. A retardation of liquid crystal is changed in a range between λ/4 and λ/2 to prevent light passing during black display.
