Abstract

PURPOSE: To perform displaying of different hues in correspondence to the presence or not of external stimuli and enhance visibility by containing specific multichromatic dyes and anisotropic dyes to a nematic liquid crystal and a mixture of this and a cholesteric liquid crystal.
CONSTITUTION: A liquid crystal material 11 is filled between substrates 1, 7 which are coated with transparent electrodes 2, 6 and of which at least one is transparent. This liquid crystal material 11 is a nematic liquid crystal of positive dielectric anisotropy as a base material 8 or mixed liquid crystals consisting in adding a cholesteric liquid crystal to this nematic liquid crystal. Further, one or more kinds of dichromatic dyes of a blue color system etc. of which the space anisotropy of absorption in a visible region is large in the molecule long axis direction and one or more kinds of anisotropic dyes of a yellow color system etc. which has virtually no or no space anisotropy of absorption in a visible region at all are contained in this base material 8. The display device of high visibility is obtainable by the use of said mixed liquid crystal materials 11.
