Beschreibung
Zusammenfassung:	The invention relates to a liquid crystal compound with negative dielectric anisotropy, a liquid crystal composition and a liquid crystal display device. The liquid crystal compound disclosed by the invention has a small response index value on the basis of maintaining a certain level of negative dielectric constant, so that the liquid crystal compound has faster response time. 本发明涉及具有负介电各向异性的液晶化合物、液晶组合物、液晶显示器件。本发明的液晶化合物在维持一定水平的负型介电常数的基础上具有小的响应指标值从而具有更快的响应时间。
