Abstract

PURPOSE: To attain a display of a high contrast by mixing a field effect (FE) type liq. crystal with two or more kinds of dichromatic dyes different from each other in dichromatic ratio and hue to make the hue of the background part of color display different from the hue of the display part.
CONSTITUTION: Transparent electrodes 11a, 12a are attached to transparent electrode substrates 11, 12 adhered to each other with spacer 13 in-between, respectively, and FE liq. crystal 14 is sealed in the space between substrates 11, 12 together with dichromatic dye 15 represented by formula I and having 7 dichromatic ratio and a blue hue and dichromatic dye 16 represented by formula II and having 4 dichromatic ratio and a yellow hue. In order to homeotropically orient crystal 14, under coat SiO2 films are formed on the electrode forming surface of substrates 11, 12 by diagonal vapor deposition, and the films are coated with dimethyl-N-octadecyl-3-aminopropoxyl-trimethoxysilyl chloride or the like having the property of vertically raising liq. crystal molecules 14. Thus, the nondisplay part (part out of an electric field) assumes a light gray color, and the display part (electric field applied part) assumes a blue color due to dye 15, resulting in a higher contrast.
