<p>Disclosed is a liquid crystalline compound which has stability to heat, light and the like, exhibits a nematic phase in a wide temperature range, has a low viscosity, adequate optical anisotropy and an adequate elastic coefficient K, and also has adequate negative dielectric anisotropy and excellent compatibility with other liquid crystalline compound. Also disclosed is a liquid crystal composition comprising the compound, which has stability to heat, light and the like, has a low viscosity, large optical anisotropy, adequate negative dielectric anisotropy and an adequate elastic coefficient K, also has a low threshold voltage, and exhibits a nematic phase having a high upper-limit temperature (i.e., a nematic-to-isotropic phase transition temperature) and a low lower-limit temperature. Specifically disclosed is a liquid crystalline compound which has a fluorine in the lateral position, and which has a specific structure having a phenylene in which a hydrogen on the benzene ring is substituted by a fluorine. Also specifically disclosed is a liquid crystal composition comprising the compound.</p> |
