(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 has excellent vertical alignment properties, image burn-in and compatibility; 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 first monomers that have a first mesogenic skeleton, at least one polymerizable group which is represented by general formula (PG1) and is connected to the first mesogenic skeleton, and at least one polar group which is connected to the mesogenic skeleton or the polymerizable group, while containing more than 0.4% by mass of one or more second monomers that have a second mesogenic skeleton and a polymerizable group which is represented by general formula (PG2) and is connected to the second mesogenic skeleton, said second monomers having a chemical structure different from the chemical structure of the first monomers; and this liquid crystal composition has excellent vertical alignment properties, image burn-in characteristics (change of the pretilt angle with time) and compatibility. The present invention also provides a liquid crystal display element which uses this liquid crystal composition.
(FR) La présente invention aborde le problème de la fourniture : d'une composition de cristaux liquides qui présente d'excellentes propriétés d'alignement vertical, de rémanence d'image et de compatibilité ; et d'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 un ou plusieurs premiers monomères qui possèdent un premier squelette mésogène, au moins un groupe polymérisable qui est représenté par la formule générale (PG1) et est relié au premier squelette mésogène, et au moins un groupe polaire qui est relié au squelette mésogène ou au groupe polymérisable, tout en contenant plus de 0,4 % en masse d'un ou de plusieurs seconds monomères qui possèdent un second squelette mésogène et un groupe polymérisable qui est représenté par la formule générale (PG2) et est relié au second squelette mésogène, lesdits seconds monomères ayant une structure chimique différente de la structure chimique des premiers monomères ; et cette composition de cristaux liquides présente d'excellentes propriétés d'alignement vertical, de caractéristiques de rémanence d'image (changement de l'angle de pré-inclinaison avec le temps) et de compatibilité. La présente invention concerne également un élément d'affichage à cristaux liquides qui utilise cette composition de cristaux liquides.
