Abstract

PURPOSE: A liquid crystal display that is provided with a liquid crystal layer containing an anthraquinone dye of a specific chemical structure as a polychromatic dye, thus improving the orientation order of the crystals and expanding the choice of available colors.
CONSTITUTION: The display has the liquid crystal layer in which at least one of anthraquinone dyes of formulaI[R1WR3 are H, hydroxyl, alkoxy, substituted alkoxy, arylmercapto, substituted arylmercapto, NHR5 (R5 is H, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, acyl, substituted acyl); R4 is aryl, substituted aryl, heterocyclic ring group, substituted heterocyclic ring group]such as red-blue system 1,4-dihydroxy-5-phenylmercapto-8-aminoanthraquinone is dissolved by 0.1W5.0, preferably 0.5W2wt% such as nematic liquid crystal, chiral nematic liquid crystal or cholesteric liquid crystal.
