Title
(EN) LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
(FR) COMPOSITION DE CRISTAUX LIQUIDES ET ÉLÉMENT D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 液晶組成物及び液晶表示素子
Abstract
(EN)
The present invention addresses the problem of providing: a liquid crystal composition which contains a polymerizable compound for producing a PSA type or PSVA type liquid crystal display element that has a sufficient pretilt angle and excellent response performance, said polymerizable compound having a sufficiently high polymerization rate and enabling an element that uses said polymerizable compound to be free from or extremely suppressed in display defects due to change of the pretilt angle; and a liquid crystal display element which uses this liquid crystal composition. The present invention provides: a liquid crystal composition which contains one or more polymerizable compounds represented by general formula (I); and a liquid crystal display element which uses this liquid crystal composition.

La présente invention aborde le problème consistant à fournir : une composition de cristaux liquides comprenant un composé polymérisable pour la production d'un élément d'affichage à cristaux liquides de type PSA ou PSVA qui présente un angle de pré-inclinaison suffisant et une performance de réponse excellente, le composé polymérisable présentant un taux de polymérisation suffisamment élevé et permettant à un élément l'utilisant de ne présentant aucun défaut d'affichage, ou un nombre de défauts d'affichage extrêmement réduit du fait du changement de l'angle de pré-inclinaison; et un élément d'affichage à cristaux liquides qui utilise cette composition de cristaux liquides. La présente invention concerne : une composition de cristaux liquides qui contient au moins un composé polymérisable représenté par la formule générale (I); et un élément d'affichage à cristaux liquides qui utilise cette composition de cristaux liquides.
