Abstract

PURPOSE: The titled mixture, containing an anthraquinone derivative, a dye of an azo compound and a liquid crystal consisting of a substance (mixture) expressed by a specific structural formula, and capable of giving a color liquid crystal display element with improved contrast.
CONSTITUTION: A dye-liquid crystal mixture containing an anthraquinone derivative or an azo compound used for a dye used in a color liquid crystal display element containing a mixture of a dye with a liquid crystal between two electrode substrates, and a liquid crystal consisting of a substance of structure expressed by formulaI[R1 is CnH2n+1- or CnH2n+1O-; R2 is CnH2n+1-, CnH2n+1O-, NC-, formula II, III or IV (n is a natural number), e.g. a biphenyl liquid crystal)] or a substance of structure expressed by formula V, e.g. phenylcyclohexane mixed liquid crystal, a mixture thereof or a mixture consisting essentially thereof.
