Abstract

PURPOSE: A compound for fluorescent liquid crystal display capable of efficiently exciting fluorescent compounds used in a low power-consumption type luminous display device, comprising a liquid crystal containing a fixed amount of liquid crystal substance with cyclohexane rings to which is added a fluorescent compound.
CONSTITUTION: A compound for fluorescent liquid crystal display which comprises Nematic phase containing more than 70wt% a liquid crystal substance, e.g., p-(4-propyl-cyclohexane-1)-cyanobenzene, etc., with a cyclohexane ring, represented by the general formula 1 (in which R is a C3 to 9 alkyl group and X is -CN, -R', -OR', and -OC2OR'(R' is a C3 to 9 alkyl group)), to which is added a coloring compound emitting fluorescence, e.g., anthrancene, tethracene, etc. Also, in place of the above-mentioned liquid crystal substance, a compound, e. g., p-(4-pentyl-cyclohexane-1-carboxylic acid)-pentoxy-phenylester, etc., represented by the general formula II (in which R is a C3 to 9 alkyl group and X is -CN, -R', -OR', and -OC2O-R'(R'is a C3 to 9 alkyl group)). The use of this compound for fluorescent liquid crystal display enables one to obtain a low power-consumption type passive display device.
