  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.

  本发明涉及一种向列液晶组合物，它可用作液晶显示装置的材料，并具有正介电各向异性（Δε），本发明还涉及一种使用这种向列液晶组合物的液晶显示装置。 本发明的液晶组合物在较宽的温度范围内具有液晶相，粘度低，在低温下具有良好的抗分解性，以及较高的比电阻和电压保持比，并且对热和光稳定；因此，使用本发明的液晶组合物有助于以较高的产量生产例如 IPS 型或 TN 型的液晶显示设备，该液晶显示设备具有良好的显示质量，并且不易出现诸如屏幕烧毁和液晶液滴污渍等显示缺陷。 使用本发明液晶组合物的液晶显示设备既能实现快速响应，又能减少显示缺陷，因此非常实用；特别是，本发明液晶组合物适用于有源矩阵驱动液晶显示设备，并可应用于 VA 模式、PSVA 模式和 TN 模式液晶显示设备。
