Abstract

PURPOSE: To facilitate the production, by specifying the initial orientation of liquid crystal and dichromatic dyes so as to make the optical utilization efficiency equal to that of chiral GH system, enable low voltage driving at 2 to 3V, and make it unnecessary to use additional elements such as quarter-wave plate.
CONSTITUTION: SiO or SiO2 is vacuum-evaporated to supporting plates 1, 2 on which electrodes 5, 6 are provided from the direction of the normal of the plates, and from the direction of 0 to 40° or 70° thereof, and oriented layers 14, 15 are formed. Liquid crystal 13 and dichromatic dyes 9 sealed between the plates 1, 2 are oriented parallel to the plates 1, 2, and at random within the flat plane. As a result, an incident light 12 and both polarized lights Ex, Ey are equivalently absorbed, and the natural light is utilized 100%, so that the equal display effect to that of chiral GH system may be obrained. When a voltage is applied from a power source 7 to electrodes 5, 6, the liquid crystal 13 and dyes 9 are arranged vertically with respect to the plates 1, 2 in the part having electric field 10, so that the display may be transparent.
