ABSTRACT:
A liquid crystal composition contains 60 to 80 parts by weight of liquid crystal compounds represented by the following general formulas (1)-(3): ##STR1## where X.sup.1 is CH.sub.3 CH.dbd.CHCH.sub.2 CH.sub.2 -- when Y.sup.1 is ##STR2## CH.sub.3 CH.dbd.CH-- or CH.sub.2 .dbd.CHCH.sub.2 CH.sub.2 -- when Y.sup.1 is ##STR3## and CH.sub.3 CH.dbd.CHCH.sub.2 CH.sub.2 -- when Y.sup.1 is ##STR4## and Z.sup.1 is alkoxy group having 1 to 5 carbon atoms when Y.sup.1 is ##STR5## and alkyl group having 1 to 5 carbon atoms when Y.sup.1 is ##STR6## where R.sup.1 is alkyl group having 3 or 4 carbon atoms, and ##STR7## where R.sup.2 is alkyl group having 1 to 5 carbon atoms, and R.sup.3 is alkoxy group having 1 to 5 carbon atoms; and 20 to 30 parts by weight of at least one liquid crystal compound represented by the following general formula: ##STR8## where X.sup.2 is CH.sub.3 CH.dbd.CH-- or CH.sub.3 CH.dbd.CHCH.sub.2 CH.sub.2 --. The composition contains at least 70 parts by weight of the liquid crystal compounds represented by formulas (1), (2) and (4).
