  There is provided a liquid crystal composition containing at least one compound represented by General Formula (a). There is also provided a liquid crystal display device using such a liquid crystal composition. The liquid crystal composition of the present invention has the following properties without suffering reductions in refractive index anisotropy (Δn) and nematic phase-isotropic liquid phase transition temperature (Tni): sufficiently low viscosity (η), sufficiently low rotational viscosity (γ1), a large elastic constant (K33), a high voltage holding ratio after UV exposure (VHR (UV)), and a negative dielectric anisotropy (Δε) with a large absolute value. A liquid crystal display device of, for example, a VA type that uses such a liquid crystal composition has a high response speed and excellent display quality with defective display being eliminated or reduced.

  本发明提供了一种液晶组合物，其中至少含有一种通式（a）所代表的化合物。还提供了一种使用这种液晶组合物的液晶显示设备。本发明的液晶组合物在不降低折射率各向异性（Δn）和向列相各向异性液相转变温度（Tni）的情况下具有以下特性：足够低的粘度（η）、足够低的旋转粘度（γ1）、较大的弹性常数（K33）、紫外线照射后较高的电压保持率（VHR (UV)）以及绝对值较大的负介电各向异性（Δε）。使用这种液晶成分的 VA 型等液晶显示设备响应速度快，显示质量优异，可消除或减少显示缺陷。
