Description

液晶組合物及液晶顯示元件、液晶顯示器
本揭露屬於液晶顯示領域,更具體地,涉及液晶組合物及包含該液晶組合物的液晶顯示元件、液晶顯示器。
早期商用的TFT-LCD產品基本採用了TN顯示模式,其最大問題是視角窄。隨著產品尺寸的增加,特別是在TV領域的應用,具有廣視野角特點的IPS顯示模式、VA顯示模式依次被開發出來並加以應用,尤其是基於VA顯示模式的改進,分別先後在各大公司得到了突破性的發展,這主要取決於VA模式本身所具有的寬視野角、高對比度和無需摩擦配向等優勢,再有就是,VA模式顯示的對比度對液晶的光學各向異性(△n)、液晶盒的厚度(d)和入射光的波長(λ)依賴度較小,必將使得VA這種模式成為極具前景的顯示技術。
但是,VA模式等的顯示元件所用的液晶介質,本身並不完美,與正介電各向異性的顯示元件相比,其存在介電偏小,反應時間比較慢,驅動電壓比較高等缺點,並且會更容易出現顯示不良、殘影等問題。
目前,應用於顯示元件的反應速度優良、各種顯示不良得到改善的液晶組合物仍然是人們期望獲得的。
為了解決現有技術中存在的問題,本發明人等進行了深入研究後驚奇地發現,藉由使用含有後述的式I所示化合物、式II所示化合物以及式III所示化合物的組合的液晶組合物,在應用於液晶顯示元件中時,表現出快速的反應速度,從而完成了本揭露。
本揭露的第一個目的在於提供一種液晶組合物,該液晶組合物具有低的旋轉黏度、快速的反應速度。
本揭露的第二個目的在於提供一種液晶顯示元件,其含有本揭露的液晶組合物。該液晶顯示元件具有快速的反應速度。

為達到上述目的,本揭露採用下述技術方案:本揭露提供液晶組合物,其包含式I所示的化合物、式II所示的化合物、一種或多種式III所示的化合物,以及,至少一種可聚合化合物:
