ABSTRACT:
A novel phenylprimidinecarboxylate derivative which, when used as a component of liquid crystal compositions, can raise the clearing point of the mesomorphic range of the liquid crystal compositions and/or increase the dielectric anisotrophy value of the compositions, and a liquid crystal compositions containing the derivative are provided, which derivative is expressed by the formula ##STR1## wherein X.sup.1 represents an alkyl or alkoxy each of 1-10 C; X.sup.2 represents a 4-substituted phenyl having an alkyl, of 1-10 C, F, Cl, Br or --CN at 4-position or a 3,4-disubstituted phenyl having f, Cl, Br or CN at 4-position and F, Cl or Br at 3-position; and either one of L or M represents .dbd.N-- and the other represents --C.dbd..
