Quest-host type liquid crystal display device

PURPOSE: To make in high contrast the display device, which has a wide angle of view while having no polarizing plate, by filling a preset liquid crystal in the clearance between the electrodes which are arranged in vertical positions. CONSTITUTION: Two transparent glass substrates, at least one of which is equipped with a transparent electrode, and treated such that their electrode surfaces are arranged at upright positions by a silicone compound or a surface active agent. There is held between the substrates a liquid crystal layer which is composed of a nematic liquid crystal having a positive dielectric anisotropy, 1 to wt. % of an optical active substance such as nematic compound and 1 to 5 wt. % of dichroic color element and in which the pitch of the liquid crystal under focal conic condition in cholesteric phase is 1/3 to 1 of the liquid crystal or the cell gap.
