  A composition exhibits a liquid crystal phase over a wide temperature range, has low viscosity, good low-temperature solubility, and high resistivity and voltage holding ratio, and is stable against heat and light. When this composition is used, IPS or TN-mode liquid crystal display devices that have good display quality and suffer less display failures such as image-sticking and drop marks are produced in high yields. Provided is a composition containing one or more compounds represented by general formula (M-1), one or more compounds represented by general formula (M-3), and one or more compounds represented by general formula (M-4). A liquid crystal display device using the composition is also provided.

  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.
