Abstract

PURPOSE: To provide a liquid crystal compsn. which is used for electrooptical elements which make good color display possible by utilizing a guest-host effect of liquid crystal, containing a specified quinophthalone coloring matter.
CONSTITUTION: An optically active substance [e.g. 4-(2-methylbutyl)-4'-cyanobiphenyl] and 0.5W3wt% quinophthalone coloring matter of formula VI (wherein X is H,Cl, Br; R1, R2 are each H, alkyl, hydroxyalkyl, alkoxyalkyl, cycloalkyl, phenyl, p-alkylphenyl, p-hydroxyphenyl, p-alkoxyphenyl, aralkyl) are added to a nematic liquid crystal substance of formula I (wherein R' is alkyl, alkoxy; x is nitro, cyano, halogen) or a host liquid crystal substance of formula II, III, IV or V.
