Abstract

PURPOSE: To reduce the power consumption of a liquid crystal chromatic display device using liquid crystal and dichroic mirror having cholesteric structure, prevent deterioration of liquid crystal, and realize practical application, by specifying the thickness of liquid crystal layer.
CONSTITUTION: A transparent electrode 2 and an orientation layer 7 are provided in glass substrates 1, 3, and liquid crystal 4 consisting of cholesteric liquid crystal or chiral nematic liquid crystal and nematic liquid crystal is sealed in. The ratio of the thickness of the liquid crystal 4 to the length of 1 period of cholesteric structure is about 0.75 to 3. When a direct-current or alternating-current voltage of about 3V is applied to the electrode 2, an incident light 8a is scattered, and the reflected light 10 corresponding to the color of the reflection characteristic of a dichroic mirror 5 reaches the eye 11. An incident light 8b in the part without electric field is not scattered, so that the light selectively transmitted through the mirror 5 is reflected by an irregular reflecting plate or a diffusion plate 6 to become a direction component 9 for the background color. When a voltage of about 7V is applied to the electrode 2, the liquid crystal molecules are arranged in vertical layout to be transparent, so that background color be visible.
