摘要：
A ferroelectric liquid crystal composition is provided which includes at least one achiral compound represented by formula (I) ##STR1## wherein each of R.sup.1 and R.sup.2 is an alkyl group having 1 to 18 carbon atoms, at least one optically active compound represented by formula (II) ##STR2## wherein R.sup.3 is an alkyl group or an alkoxy group having 1 to 18 carbon atoms, R.sup.4 is an alkyl group having 2 to 18 carbon atoms, X is a single bond, --COO--, --OCO--, --N.dbd.CH--, --CH.dbd.N--, --OCH.sub.2 -- or --CH.sub.2 O--, each of m and n is an integer of 1 or 2, and the symbol * is an asymmetric carbon atom, and at least one compound represented by formula (III) ##STR3## wherein each of ##STR4## R.sup.5 is an alkyl group or an alkoxy group having 1 to 18 carbon atoms, Y is a single bond, --CH.sub.2 O-- or --OCH.sub.2 --, p is an integer of 0 or 1, and Z is an alkyl group having 1 to 18 carbon atoms or --C*H(CH.sub.3)--O--R.sup.6, wherein R.sup.6 is an alkyl group having 1 to 18 carbon atoms and the symbol * represents an asymmetric carbon atoms.
