一种具有高可靠性的液晶组合物及其应用
摘要：
本发明提供了一种具有高可靠性的液晶组合物及其应用，所述液晶组合物按重量份计，包括以下组分：(1)5～40份通式I所代表的化合物；(2)20～70份通式II所代表的化合物；(3)1～40份通式III所代表的化合物；(4)0～30份通式IV所代表的化合物。本发明所提供的液晶组合物具有高的电压保持率、低的离子浓度、优异的光稳定性，适合的光学各向异性、良好的低温互溶性、大的弹性常数以及良好的热稳定性，可有效改善液晶显示器存在的可靠性问题，有效地改善液晶显示器的残像问题，提升液晶显示器的显示质量和使用寿命。因此，本发明所提供的液晶组合物适用于高可靠性的TN、IPS及FFS型TFT液晶显示装置，尤其适用于IPS及FFS液晶显示装置。
摘要（英）：

The invention provides a liquid crystal composition with the high reliability and application thereof. The liquid crystal composition is prepared from, by weight, 5-40 parts of a compound represented by the general formula I (the formula is shown in the description), 20-70 parts of a compound represented by the general formula II (the formula is shown in the description), 1-40 parts of a compound represented by the general formula III (the formula is shown in the description) and 0-30 parts of a compound represented by the general formula IV (the formula is shown in the description). The liquid crystal composition has the high voltage holding ratio, the low ion concentration, the excellent light stability, the appropriate optical anisotropy, the good low-temperature intersolubility, the high elastic constant and the good thermal stability and can effectively solve the reliability problem of a liquid crystal display, effectively solve the residual image problem of the liquid crystal display, improve the display quality of the liquid crystal display and prolong the service life of the liquid crystal display. Therefore, the liquid crystal composition is suitable for high-reliability TN, IPS and FFS type TFT liquid crystal display devices and especially suitable for IPS and FFS type liquid crystal display devices.
