ABSTRACT:
A mesomorphic compound represented by the following formula (I): ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 independently denote methyl group or a mesomorphic residual group, at least one of R.sub.1, R.sub.2 and R.sub.3 being a mesomorphic residual group having an optically active group of the formula below as a terminal flexible group: ##STR2## wherein R.sub.4 is an alkyl group having 1-12 carbon atoms; n is an integer of 0-10; m is an integer of 1-10; and L is an integer of 1-100. The mesomorphic compound is usable for constituting a liquid crystal composition and a liquid crystal device having a large picture area and capable of showing an improved switching characteristic and a good impact resistance.
