Abstract: A composition for a liquid crystal display containing at least one nematic liquid crystalline material having dissolved therein at least one anthraquinonic dye of the formula ##STR1## wherein R is a linear or branched C.sub.7-15 alkyl group.

Abstract: A composition for nematic liquid crystal color display elements, said composition comprising at least one anthraquinonic dye represented by the following formula ##STR1## wherein X and Y are identical or different and represent --NH.sub.2 or --OH; Z represents halogen, --OR, --NHR, ##STR2## --CONHR.sub.2 or --COOR.sub.2, in which R represents an alkyl group having 1 to 15 carbon atoms or a lower alkyl group optionally substituted by --OH, ##STR3## R.sub.1 represents hydrogen, halogen, --OH, --OCH.sub.3, an alkyl group having 1 to 15 carbon atoms, or a methoxy group optionally substituted by ##STR4## and R.sub.2 is a phenyl group, an alkyl group having 2 to 5 carbon atoms or a cyclohexyl group; and n is an integer of 1 or 2 provided that when X is --NH.sub.2 and Y is --OH, and when X and Y are both --OH, n is an integer of 1, and when n represents an integer of 2, the two Z's may be identical or different dissolved in at least one nematic liquid crystal.
