A mesomorphic compound represented by the formula:
wherein R₁ denotes an alkyl group having 1 - 16 carbon atoms; R₂ denotes an alkyl group having 2 - 10 carbon atoms; X denotes a single bond or -0-; Y denotes -OCH₂-, -OCH₂- or -O-;
Z denotes a single bond,
respectively and independently denote
k, l and n are respectively 0, 1 or 2 satisfying the relation of k+l+n = 2 or 3; C* denotes an asymmetric carbon atom. The mesomorphic compound, when added as a component, provides a liquid crystal composition showing an improved field respective characteristic or is effective in preventing occurrence of a reverse domain.
