ABSTRACT:
Ester compounds having a pyrimidine ring, using as their raw material, substituted pyrimidinols in place of expensive p-substituted phenols, and also useful as a material for liquid crystal display elements are provided which esters are expressed by the general formula ##STR1## wherein R represents an alkyl or alkoxy group of 1 to 10 carbon atoms; X represents a halogen atom of F, Cl or Br, cyano group or an alkyl or alkoxy group of 1 to 10 carbon atoms; ##STR2## represents ##STR3## and n is 0 or 1.
