ABSTRACT:
A ferroelectric chiral smectic liquid crystal composition, comprising at least one optically active compound represented by the following formula (I): ##STR1## wherein R.sub.1 and R.sub.2 respectively denote a linear or branched alkyl group having 1-18 carbon atoms capable of having a substituent, at least one of R.sub.1 and R.sub.2 being optically active; X.sub.1 denotes --O--, ##STR2## and X.sub.2 denotes a single bond, --O--, ##STR3## and at least one compound represented by the following formula (II): ##STR4## wherein R.sub.3 and R.sub.4 respectively denote a linear or branched optically inactive alkyl group having 1-18 carbon atoms capable of having an alkoxy group of 1-12 carbon atoms; X.sub.3 and X.sub.4 respectively denote a single bond, --O--, ##STR5## and m and n are respectively 0, 1 or 2 with proviso that both of m and n are not 0.
