摘要：
A liquid crystal composition contains a mesomorphic compound represented by the following formula (A): ##STR1## wherein R.sub.1 and R.sub.2 independently denote a linear or branched alkyl group having 1-18 carbon atoms; X.sub.1 denotes a single bond, --O--, --CO--O-- or --O--CO--; and A.sub.1 denotes ##STR2## and a mesomorphic compound represented by the following formula (B): ##STR3## wherein R.sub.3 denotes a linear or branched alkyl group having 1-18 carbon atoms; X.sub.2 and X.sub.3 independently denote a single bond, --O--, --CO--O-- or --O--CO--; m is an integer of 3-16; and A.sub.2 denotes ##STR4## or ##STR5## The liquid crystal composition may preferably be formulated as a chiral smectic liquid crystal composition. The liquid crystal composition is useful in providing a liquid crystal device using the liquid crystal composition with a good alignment characteristic, a good drive characteristic, and a high and stable contrast ratio.
