摘要：
New liquid crystal compounds having a low viscosity and nevertheless having a high transparent point and a broad nematic temperature range, and liquid crystal compositions containing the same are provided. The compounds are liquid-crystalline halogenobenzene derivatives expressed by the general formula ##STR1## wherein R represents an alkyl group having 1 to 10 carbon atoms; ##STR2## and X and Y each are H, F or Cl, at least one of X and Y being F or Cl.
