A liquid crystal composition, comprising: at least one mesomorphic compound represented by the following formula (I): ##STR1## wherein R.sup.1 and R.sup.2 independently denote a linear or branched alkyl group having 1-18 carbon atoms capable of including one or non-neighboring two or more methylene groups which can be replaced with at least one species of --O--, --CO--, --COO--, --OCO--, --OCOO-- or --CH(X)-- with the proviso that --O-- cannot directly be connected to --O-- and X denotes halogen; Z.sup.1 denotes --COO-- or --CH.sub.2 O--; X.sup.1 and X.sup.2 independently denote a single bond, --O--, --COO--, --OCO--, --CO-- or --OCOO--; A.sup.1 denotes a single bond, ##STR2## Y.sup.1 and Y.sup.2 independently denote hydrogen, halogen, --CH.sub.3 -- or CF.sub.3 --; and at least one mesomorphic compound represented by the following formula (II): ##STR3## wherein R.sup.3 and R.sup.4 independently denote a linear or branched alkyl group having 1-18 carbon atoms capable of including one or non-neighboring two or more methylene groups which can be replaced with at least one species of --O--, --CO--, --COO--, --OCO--, --OCOO-- or --CH(X)-- with the proviso that --O-- cannot directly be connected to --O-- and X denotes halogen; X.sup.3 and X.sup.4 independently denotes a single bond, --O--, --COO--, --OCO-- or --CO--; Z.sup.2 denotes a single bond, --COO-- or --OCO--; A.sup.2, A.sup.3 and A.sup.4 independently denote a single bond, ##STR4## Y.sup.3 and Y.sup.4 independently denote hydrogen, halogen, --CH.sub.3 or --CF.sub.3 ; and k is 0 or 1 with the proviso that X.sup.3 is a single bond when A.sup.2 is a single bond, and X.sup.4 is a single bond when A.sup.3 is a single bond and k is 0. The liquid crystal composition is easily aligned by a simple rubbing method to provide a uniform monodomain and further provides wider driving voltage and temperature margins effective for providing a practical ferroelectric liquid crystal device.
