Abstract
A mesomorphic compound of the formula (I) according to claim 1 characterized by having at least one cyclic group selected from .beta. class including, e.g., thiazole-2,5-diyl, benzoxazole-2,5-diyl, indan-2,5-diyl, and quinoxaline-2,6-diyl and also having a linkage of Y.sup.1 (CH.sub.2).sub.m Y.sup.2, where Y.sup.1 and Y.sup.2 are --CH.sub.2 --, --O--, --COO-- or --OCO-- and m is 1-16, is suitable as a component for a liquid crystal composition providing improved response characteristics. A liquid crystal device is constituted by disposing the liquid crystal composition between a pair of substrates. The liquid crystal device is used as a display panel constituting a liquid crystal apparatus providing good display characteristics.
