ABSTRACT:
A novel liquid crystal ester compound which is useful as a component for TN type nematic liquid crystal composition, raising its nematic-isotropic liquid phase-isotropic liquid phase transition point without increasing its viscosity and a liquid crystal composition containing the same are provided, which ester compound is expressed by the formula ##STR1## wherein R.sup.1 represents an alkyl group or an alkoxy group each of 1 to 10 carbon atoms; ##STR2## represents ##STR3## Y represents -- COO--or --OCO--; any of ##STR4## n represents 0 or 1; and Z represents an alkyl group or an alkoxy group each of 1 to 10 carbon atoms, or a halogen atom of F, Cl or Br.
