ABSTRACT:
The present invention provides a ferroelectric liquid crystal composition wherein the phase transition series of the composition assumes an order of isotropic liquid.fwdarw.cholesteric phase.fwdarw.chiral smectic C phase starting from the high temperature and to a switching element good in contrast, and memory properties using the same. The composition comprises a composition that contains a component A of a compound having the formula: ##STR1## and/or a compound having the formula: ##STR2## wherin R.sup.1 and R.sup.2 represent each an alkyl group having 1 to 18 carbon atoms;
