Description

液晶组合物及其显示器件 技术领域
本发明涉及一种液晶组合物，特别涉及一种具有较大的光学各向异性、较大的介电各向异性、较高的清亮点、较快的响应速度、较高的电阻率、良好的高温稳定性以及UV稳定性的液晶组合物，以及包含该液晶组合物的液晶显示器件。
背景技术
液晶材料是在一定的温度下，既具有液体的流动性又具有晶体的各向异性的有机棒状小分子化合物的混合物。液晶材料主要被用作显示器中的电介质，其原因在于这类物质的光学性能可通过施加的电压而改变。液晶显示器(liquid crystal display)为利用液晶光电变化的显示器，其具有体积小、重量轻、低电力消耗与显示品质佳等吸引人的优点，因此近年来已经成为平面显示器的主流。现有的液晶显示器采用的电光学模式是例如扭转相列型(TN)-，超扭转相列型(STN)-，光学补偿弯曲(OCB)-和电控双折射(ECB)-模式及它们的各种变体的模式。所有的这些模式都使用电场，该电场基本上垂直于基板，或者是垂直于液晶层，除这些模式外，也存在采用基本上平行于基板，或者是液晶层的电场的电光学模式，如平面内切换模式。
对于此类显示器，需要具有改进性能的新型液晶介质。特别地，对于许多应用类型而言，包含液晶组合物的液晶介质必须具有合适的宽范围的向列相及适当的双折射率，且介电各向异性应当足够高以允许合理低的操作电压。液晶显示材料还需要有合适宽的向列相温度范围、高温稳定性等性能，以满足在各种环境中均能保持良好显示的要求。
适用于LCD和特别地适用于TFT显示器的液晶组合物例如从JP07-181439，EP0667555，EP0673986，DE19509410，DE19528106，DE19528107，WO9623851和WO9628521是已知的。然而，这些液晶组合物具有显著的缺点。它们中的大部分，除了其他缺点外，尤其导致不利的长的响应时间，具有过低的电阻率且需要过高的操作电压。
因此，在液晶材料领域，特别需要具有实际应用所需性能，如较高的向列相温度上限，适当的光学各向异性，良好的介电各向异性、高温稳定性、较高的电阻率的液晶组合物。
发明内容
本发明的发明目的是提供一种具有较大的光学各向异性、较大的介电各向异性、较高的清亮点、较快的响应速度、较高的电阻率、良好的高温稳定性以及UV稳定性的液晶组 合物，所述液晶组合物适用于液晶显示器中，特别是具有快速响应需求的液晶显示器，使得液晶显示器在恶劣的环境中工作时，图像显示效果好，无拖影现象。
