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，特别涉及一种具有合适的光学各向异性、合适的介电各向异性、较高清亮点、较快的响应速度以及良好的高温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。根据液晶材料性质的不同，各种相态的液晶材料大都已开发用于液晶显示器件中。
对于液晶显示器来说，具备良好的化学和热稳定性、良好的对电场和电磁辐射的稳定性、适当的光学各向异性、较快的响应速度及较低的阈值电压的液晶化合物与液晶介质是符合目前需求的。由于液晶通常作为多种组分的混合物使用，各组分之间的彼此互溶则显得尤为重要，而依据不同的电池类型和应用领域，液晶必须要满足不同的要求，如电导率、介电各向异性和光学各向异性等，但是在现有技术中显著存在的缺点是较长的响应时间，较低电阻率且操作电压过高等，如EP0673986、DE19528106、DE19528107。
响应速度是液晶显示器的重要评价指标，响应速度过慢，显示画面就会出现拖影现象，因此要求液晶显示器具有快的响应速度。为了提高液晶显示器的响应速度，可以选用减小盒厚、改良驱动方式、提高驱动电压、采用快速响应的液晶组合物等方法。但不管采用何种方法，总会带来液晶显示器其他性能的削弱。如改变驱动方式，往往会导致IC驱动成本升高、电路更为复杂；提高驱动电压，功耗也会随之增加；减小盒厚，会增加生产工艺的难度，造成盒厚不均等缺陷，导致液晶显示器良率的下降。
以上改良方式都是从液晶显示屏的制作着手，实际上，液晶面板生产商会更倾向于选择快响应速度的液晶材料来改善液晶显示器的响应速度。但液晶材料的各项性能是相互制约的，加快响应速度往往会带来清亮点的降低，导致液晶显示屏不能在高温环境下工作，高低温可靠性能降低，严重时会导致液晶显示器在低温下无法正常显示。
