  The liquid crystal composition of the present invention can be used in a liquid crystal display element of an IPS type or a TN type in which display defects such as burn-in and dropping marks in high speed response are unlikely to be generated. Since the liquid crystal composition contains a component which is a dielectrically positive component including a dielectrically positive compound and a dielectrically neutral component of which dielectric anisotropy is greater than -2 and less than +2, the liquid crystal composition has excellent characteristics that the liquid crystal composition has a liquid crystal phase in a wide temperature range, low viscosity, excellent solubility at a low temperature, high specific resistance and a high voltage holding ratio, and is stable with respect to heat and light.

  The present invention relates to a nematic liquid crystal composition which is useful as a material used for liquid crystal display devices and which has a positive dielectric anisotropy (Δε), and the present invention further relates to a liquid crystal display device using such a nematic liquid crystal composition. The liquid crystal composition of the present invention has a liquid crystal phase in a broad temperature range, a low viscosity, good resistance to resolution at low temperature, and high specific resistance and a voltage holding ratio and is stable to heat and light; hence, use of the liquid crystal composition contributes to production of a liquid crystal display device of, for example, an IPS type or a TN type in a good yield, the liquid crystal display device having good display quality and being less likely to suffer from defective display such as screen burn-in and stains of liquid crystal droplets. A liquid crystal display device using the liquid crystal composition of the present invention enables both quick response and a reduction in defective display and is therefore practical; in particular, the liquid crystal composition is useful to active-matrix-driving liquid crystal display devices and can be applied to VA-mode, PSVA-mode, and TN-mode liquid crystal display devices.
