  The present invention provides a liquid crystal composition having positive dielectric anisotropy and containing at least one compound represented by general formula (LC0): and at least one compound represented by general formula (LC1): R11A11-Z11m11A12-Z12-A13-R12  (LC1) The liquid crystal composition according to the present invention has refractive index anisotropy (Δn) adjusted to the desired level and a decrease in nematic phase-isotropic liquid phase transition temperature (Tni) and an increase in the nematic phase lower limit temperature are suppressed so as to achieve a sufficiently low viscosity (η) without degrading the nematic phase temperature range. When the liquid crystal composition of the present invention is used to produce a liquid crystal display device, a highly practical and highly reliable liquid crystal display device with high response speed and capacity for low-voltage drive is obtained.

  A nematic liquid crystal composition of the present invention is used in liquid crystal display devices of the TN mode, OCB mode, ECB mode, IPS mode, or VA-IPS mode. The liquid crystal composition has positive dielectric anisotropy. Since the refractive index anisotropy and the nematic phase-isotropic liquid phase transition temperature are decreased and the increase in the lower limit temperature of the nematic phase is suppressed, the viscosity of the liquid crystal composition is sufficiently low without degrading the nematic phase temperature range. The liquid crystal composition also offers excellent features such as high-speed response, good display quality, and less display failures and is thus suitable as a practical liquid crystal composition.

  The nematic liquid crystal composition exhibits a positive dielectric anisotropy (Δε), the liquid crystal composition being useful as a liquid crystal display material, and a liquid crystal display element using the same. The liquid crystal composition of the present invention has a large absolute value of dielectric anisotropy thereof and a low viscosity. By using this liquid crystal composition, it is possible to provide a liquid crystal display element which has a high contrast, high-speed responsiveness, and good display quality in which image sticking and display defects are not generated. The liquid crystal display element using the liquid crystal composition is a useful display element which realizes both high-speed response and suppression of display defects. In particular, the liquid crystal display element is useful as a liquid crystal display element for active-matrix driving, and can be applied to, for example, an IPS-type or TN-type liquid crystal display element.

  There is provided a nematic liquid crystal composition which has a positive dielectric anisotropy (Δ∈) and is useful as a liquid crystal display material, and to a liquid crystal display device using it. The liquid crystal composition has a dielectric anisotropy with a high absolute value and low viscosity. The liquid crystal display device using the liquid crystal composition has high contrast, high-speed response, and high display quality, and thus image sticking and display defects are not caused. The liquid crystal display device that uses the liquid crystal composition is a useful liquid crystal display device in which high-speed response is achieved and generation of display defects is reduced. The liquid crystal display device is particularly useful as an active matrix driving liquid crystal display device and can be applied to liquid crystal display devices with an IPS mode, a TN mode, or the like.
