Title (EN) ALIGNMENT ASSISTANT, LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY ELEMENT
(FR) ASSISTANT D'ALIGNEMENT, COMPOSITION DE CRISTAUX LIQUIDES ET ÉLÉMENT D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 配向助剤、液晶組成物及び液晶表示素子
Abstract:
(EN) Provided is an alignment assistant which is capable of ensuring storage stability if added into a liquid crystal composition, and which causes liquid crystal molecules to vertically align spontaneously even if a PI layer is omitted. Also provided are: a liquid crystal composition which exhibits excellent storage stability and which enables vertical alignment of liquid crystal molecules even if a PI layer is omitted; and a liquid crystal display element which uses this liquid crystal composition. An alignment assistant according to the present invention is arranged between two substrates together with liquid crystal molecules and causes the liquid crystal molecules to align spontaneously. This alignment assistant is characterized by containing a first compound which contains at least one first affinity group that has an affinity for the substrates and a second compound which contains at least one second affinity group that has an affinity for the substrates, while having a lower polarity than the first affinity group.
(FR) L'invention concerne un assistant d'alignement qui est en mesure d'assurer une stabilité de stockage s'il est ajouté dans une composition de cristaux liquides et qui provoque l'alignement vertical spontané des molécules de cristal liquide, même si une couche PI est omise. L'invention concerne également : une composition de cristaux liquides qui présente une excellente stabilité au stockage et qui permet un alignement vertical des molécules de cristal liquide même si une couche PI est omise ; et un élément d'affichage à cristaux liquides qui utilise cette composition de cristaux liquides. Un assistant d'alignement selon la présente invention est agencé entre deux substrats conjointement avec des molécules de cristal liquide et provoque l'alignement spontané des molécules de cristal liquide. Cet assistant d'alignement est caractérisé en ce qu'il contient un premier composé qui contient au moins un premier groupe d'affinité qui présente une affinité pour les substrats et un deuxième composé qui contient au moins un deuxième groupe d'affinité qui présente une affinité pour les substrats, tout en présentant une polarité inférieure à celle du premier groupe d'affinité.
(JA) 液晶組成物に添加した際に保存安定性を確保でき、PI層を省略しても、液晶分子を自発的に垂直配向させる配向助剤を提供する。また、保存安定性に優れ、PI層を省略しても、液晶分子の垂直配向が可能な液晶組成物、及び該液晶組成物を用いた液晶表示素子を提供する。 本発明の配向助剤は、2つの基板間に液晶分子とともに配置され、前記液晶分子を自発的に配向させる。この配向助剤は、前記基板に対する親和性を有する少なくとも1つの第1の親和性基を含む第1の化合物と、前記基板に対する親和性を有し、かつ前記第1の親和性基より極性が低い少なくとも1つの第2の親和性基を含む第2の化合物と、を含有することを特徴とする。
