| 摘要 |
The present invention relates to a nematic liquid crystal composition having a negative dielectric anisotropy (”µ) which can be suitably used as a material for liquid crystal displays and to a liquid crystal display element including the nematic liquid crystal composition. The liquid crystal composition according to the present invention has a sufficiently low viscosity (·), a sufficiently low rotational viscosity (³1), a high elastic constant (K 33 ), and a negative dielectric anisotropy (”µ), the absolute value of the negative dielectric anisotropy being large, without a reduction in the refractive index anisotropy (”n) or the nematic phase-isotropic liquid phase transition temperature (T ni ) thereof. By using the liquid crystal composition, it is possible to provide a liquid crystal display element, such as a VA-type liquid crystal display element, which eliminates or reduces the risk of a faulty display and realizes high display quality and a highspeed response. The liquid crystal display element including the liquid crystal composition according to the present invention may be suitably used as a liquid crystal display element for active-matrix driving and may also be used as, for example, a VA-type or PSVA-type liquid crystal display element. |
