Title (EN) LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE HAVING SAME
(FR) COMPOSITION À CRISTAUX LIQUIDES ET DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES LA COMPRENANT
(ZH) 液晶组合物及其液晶显示器件
Abstract:
(EN) Disclosed is a liquid crystal composition, containing: at least one compound of general formula I; at least one compound of general formula II and at least one compound of general formula III, wherein the liquid crystal composition has a high optical anisotropy, and also has a relatively large elastic constant K 11 and K 33 while maintaining a relatively high clearing point, an appropriate dielectric anisotropy and a good low temperature miscibility. Also disclosed is a liquid crystal display device containing the liquid crystal composition of the present invention. The display device has advantages of fast response, high contrast, and a wide temperature range, and thus has a good display effect and a large range of applicability.
(FR) L'invention concerne une composition à cristaux liquides, contenant : au moins un composé de formule générale I ; au moins un composé de formule générale II ; et au moins un composé de formule générale III, la composition à cristaux liquides ayant une anisotropie optique élevée et ayant également des constantes élastiques K11 et K33 relativement grandes tout en conservant un point d'effacement relativement élevé, une anisotropie diélectrique appropriée et une bonne miscibilité à basse température. L'invention concerne également un dispositif d'affichage à cristaux liquides contenant la composition à cristaux liquides selon la présente invention. Le dispositif d'affichage présente les avantages d'une réponse rapide, d'un contraste élevé et d'une large plage de température de fonctionnement et présente ainsi un bon effet d'affichage et une large gamme d'applicabilité.
(ZH) 本发明提供了一种液晶组合物,所述液晶组合物包含:至少一种通式Ⅰ的化合物;至少一种通式Ⅱ的化合物以及至少一种通式Ⅲ的化合物,所述液晶组合物具有较高的光学各向异性,在维持相对高的清亮点、适当的介电各向异性以及较好的低温互溶性的同时,还具有相对大的弹性常数K 11和K 33,本发明还提供了一种包含本发明所述液晶组合物的液晶显示器件,所述显示器件具有响应快、对比度高、温宽范围大等优点,从而具有良好的显示效果以及较大的适用范围。
