Abstract

PURPOSE: To control the display color of a color liquid crystal display element and thereby to make it possible to select the desired color, by forming the liquid crystal material layer of the element from a polygenetic dye and at least two liquid crystal materials which differ in the extent to which they affect the light absorption wavelength region of the dye.
CONSTITUTION: In a color liquid crystal display element of a guest/host system, having a liquid crystal material layer contining a polygenetic dye and liquid crystal materials, the liquid crystal material layer includes at least one polygenetic dye such as 6-ethoxy-4'-N,N'-dimethylaminophenylazobenzenethiazol, and further includes a suitable amount of a mixture of at least two liquid crystal materials which differ in the extent to which they affect the light absorption wavelength region of the dye, such as compounds represented by formulas I, II and III, wherein X and Y are R, OR, CN or NH2 and R is alkyl or alkenyl.
