Liquid crystal display device |
摘要 |
A retardation film type guest host liquid crystal display is arranged to reduce coloring in dark representation and to be energy-effective. The liquid crystal display includes a liquid crystal layer containing a given amount of dichroic dye and having a twist alignment, a reflective plate, and a phase plate located between the liquid crystal layer and the reflective plate. The phase plate has a slow axis set at 45 degrees against the alignment direction of the liquid crystal and a retardation set at a half of a phase difference between an ordinary ray before reflection by said reflective plate and an extraordinary ray after reflection.
