Abstract

PURPOSE: To provide a liquid crystal display device having an improved degree of orientation order and selectivity in usable color, by providing a liquid crystal layer in which a specified anthraguinone dye as a polychromic dye is dissolved.
CONSTITUTION: A liquid crystal display device is provided with a liquid crystal layer in which at least one anthraguinone dye of formulaI[wherein R1 is (substd.) anilide; R2, R3 are each H, nitro, hydroxy, (substd.) amino with the proviso that either one of R2 and R3 is always a group other than H] such as a compd. of formula II or III as a polychromic dye is dissolved. Conventional compds. proposed as anthraquinone dyes for liquid crystals are chemically stable and has resistance to light such as ultraviolet light and good solubility in liquid crystals, but are lacking in a high degree of order, wide absorption wave range or required absorption wave band. By using the above anthraquinone dye, both the degree of orientation order and selectivity in usable color are improved.
