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 denotes a linear or branched alkyl group having 1-18 carbon atoms capable of having a subtituent; X.sub.1 denotes a single bond, ##STR2## Z denotes a single bond or ##STR3## denotes ##STR4## and n is an integer of 1-12; and at least one compound represented by the following formula (II): ##STR5## wherein R.sub.2 and R.sub.3 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.2 and X.sub.3 respectively denote a single bond, ##STR6## and p and q are respectively 0, 1 or 2 with proviso that both of p and q are not 0.
