  The present invention provides a liquid crystal composition having a negative dielectric anisotropy whose absolute value is large, and a low viscosity, and also provides a VA type liquid crystal element using the same. Disclosed is a liquid crystal composition containing a compound represented by the general formula (I) and an alkenyl compound represented by the general formula (II): By combining the liquid compounds according to the present invention, a liquid crystal composition having a low viscosity and a negative dielectric anisotropy could be obtained while nearly maintaining physical properties such as refractive anisotropy. By using the composition, a liquid crystal element having excellent reliability, capable of maintaining a high voltage retention until a high temperature region, is provided, and the display is very applicable as a VA type, ECB type, or IPS type liquid crystal display, and is particularly effective for speeding up response without thinning cell gaps.

  The invention provides a liquid crystal compound having stability to heat, light and so forth, a wide temperature range of a nematic phase, a small viscosity, a suitable optical anisotropy, a suitable elastic constant K33, a suitable and negative dielectric anisotropy, and an excellent compatibility with other liquid crystal compounds. The invention provides a liquid crystal composition containing the compound described above and having stability to heat, light and so forth, a small viscosity, a suitable optical anisotropy, a suitable and negative dielectric anisotropy, a suitable elastic constant K33, a low threshold voltage, a high maximum temperature of a nematic phase, and a low minimum temperature of the nematic phase. The invention also provides a liquid crystal display device having a short response time, a small power consumption, a low driving voltage, and a large contrast, and containing the composition described above which can be used in a large temperature range. For example, a liquid crystal compound having four or more rings in which the central ring has 2,3-difluorophenoxy such as trans-4′-[2,3-difluoro-4-(trans-4-propylcyclohexyl)phenoxymethyl]-trans-4-pentylbicyclohexyl is provided. Further provided is a liquid crystal composition containing the compound, and a liquid crystal display device using this liquid crystal composition.
