A dichroic dye for coloring liquid crystal compositions are disclosed which is represented by the following general formula: ##STR1## in which Dye 1 and Dye 2 each represents a group of atoms necessary to form a linear dye structure containing an azo, azomethine or ester group; X represents a halogen atom; and n represents an integer of from 1 to 10. The dye is suited for use in color liquid crystal display devices, e.g., of guest-host type.

Dichoric dye for color liquid crystals having halogen substituted in

A dichromatic coloring matter for a colored liquid crystal display element comprising a compound of the general formula: ##STR1## where A and B each stand for ##STR2## where n is 0, 1, 2, 3 or 4, and X and Y each stand for ##STR3## where R.sub.1 and R.sub.2 stand for an alkyl group or hydrogen, --R (alkyl group) or --OR (alkoxy group).
