Title (EN) LIQUID CRYSTAL COMPOSITION AND USE THEREOF
(FR) COMPOSITION DE CRISTAUX LIQUIDES ET SON UTILISATION
(ZH) 一种液晶组合物及其应用
Abstract:
(EN) Disclosed are a liquid crystal composition and the use thereof. The liquid crystal composition contains: at least one compound of general formula I and at least one polymerizable compound of general formula II. The liquid crystal composition provided by the present invention has a suitable optical anisotropy, a suitable dielectric anisotropy, and a better pretilt angle consistency while maintaining a relatively high clearing point, and the drop mura is good. When the liquid crystal composition is applied to a PSA liquid crystal display, same has an excellent display effect.
(FR) La présente invention concerne une composition de cristaux liquides et son utilisation. La composition de cristaux liquides contient : au moins un composé de formule générale (I) et au moins un composé polymérisable de formule générale (II). La composition de cristaux liquides selon la présente invention présente une anisotropie optique appropriée, une anisotropie diélectrique appropriée, et une meilleure cohérence d'angle de pré-inclinaison tout en conservant un point de dégagement relativement élevé, et l'effet Mura est bon. Lorsque la composition de cristaux liquides est appliquée à un affichage à cristaux liquides PSA, ce dernier présente un excellent effet d'affichage.
(ZH) 本发明公开了一种液晶组合物及其应用,所述液晶组合物包含:至少一种通式Ⅰ的化合物以及至少一种通式Ⅱ的可聚合化合物。本发明提供的液晶组合物具有适合的光学各向异性、适合的介电各向异性以及在维持相对高的清亮点的同时,还具有较好的预倾角一致性,drop mura表现良好。所述液晶组合物应用于PSA型液晶显示器时,具有优异的显示效果。
