    • The present invention relates to a nematic liquid crystal composition useful as a liquid crystal display material and showing a negative value of dielectric anisotropy (Δε), and to a liquid crystal display device using the liquid crystal composition.
      The present invention provides a liquid crystal composition which causes little dropping marks during manufacture without degrading characteristics, such as dielectric anisotropy, viscosity, an upper limit temperature of a nematic phase, γ 1 , and the like, and image sticking of a display device.
      The liquid crystal display device of the present invention has excellent fast response, the characteristic of causing little image sticking, and the characteristic of causing little dropping marks due to its manufacture, and are thus particularly useful for VA-mode and PSVA-mode liquid crystal display devices for active matrix driving and can be applied to liquid crystal display devices such as liquid crystal TV, a monitor, and the like.
    • 本发明涉及用作液晶显示材料并显示介电各向异性(“μ”)的负值的向列型液晶组合物以及使用该液晶组合物的液晶显示装置。 本发明提供了一种液晶组合物,其在制造过程中几乎没有劣化特性,例如介电各向异性,粘度,向列相的上限温度,等等,以及显示装置的图像粘附。 本发明的液晶显示装置具有优异的快速响应性,几乎没有图像残留的特征,以及由于其制造而引起的滴落痕迹的特征,因此对VA模式和PSVA模式液晶特别有用 用于有源矩阵驱动的显示装置,并且可以应用于诸如液晶电视,监视器等的液晶显示装置。
