| 摘要 |
The present invention relates to a nematic liquid crystal composition with negative dielectric anisotropy (”µ) useful as a liquid crystal display material, and to a liquid crystal display device using the composition. The liquid crystal composition of the present invention provides a liquid crystal composition that has sufficiently low viscosity (·), sufficiently low rotational viscosity (³1), high elastic modulus (K 33 ), and negative dielectric anisotropy (”µ) with a large absolute value without decreasing the refractive index anisotropy (”n) and nematic phase-isotropic liquid phase transition temperature (T ni ). A liquid crystal display device of VA-mode or the like that uses this composition is also provided, which has less or no display failures. The liquid crystal display device that uses the liquid crystal composition of the present invention is useful as an active-matrix-driving liquid crystal display device and can be used as a liquid crystal display device of VA-mode PSVA-mode, or the like. |
