Title
(EN) LIQUID CRYSTAL ALIGNMENT TREATMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
(FR) AGENT DE TRAITEMENT D'ALIGNEMENT DE CRISTAUX LIQUIDES, FILM D'ALIGNEMENT DE CRISTAUX LIQUIDES ET ÉLÉMENT D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 液晶配向処理剤、液晶配向膜及び液晶表示素子
Abstract
(EN)
Provided are: a liquid crystal alignment treatment agent that can be used to produce a liquid crystal alignment film that has outstanding preservation stability, provides high adhesiveness (adhesion) between substrates of a liquid crystal display element, and can suppress air bubbles generating within the liquid crystal display element as well as detachment of the element even in an environment exposed to high temperature and high humidity for a long period of time; a liquid crystal alignment film obtained by using said agent; and a liquid crystal display element. The liquid crystal alignment treatment agent contains a compound including a group represented by a formula [1]. (* represents the site of bonding with another structure.)
(FR)
L'invention concerne : un agent de traitement d'alignement de cristaux liquides qui peut être utilisé pour produire un film d'alignement de cristaux liquides qui présente une excellente stabilité de conservation, fournit une adhésivité (adhérence) élevée entre des substrats d'un élément d'affichage à cristaux liquides, et peut supprimer des bulles d'air générant à l'intérieur de l'élément d'affichage à cristaux liquides ainsi que le détachement de l'élément même dans un environnement exposé à une température élevée et une humidité élevée pendant une longue période de temps ; un film d'alignement de cristaux liquides obtenu en utilisant ledit agent ; et un élément d'affichage à cristaux liquides. L'agent de traitement d'alignement de cristaux liquides contient un composé comprenant un groupe représenté par la formule [1]. (* représente le site de liaison à une autre structure.)
(JA)
保存安定性に優れ、液晶表示素子の基板間の接着性(密着性)が高く、長時間、高温高湿に曝される環境でも、液晶表示素子内の気泡の発生や素子の剥がれを抑制できる液晶配向膜を作製できる液晶配向処理剤、これから得られる液晶配向膜、及び液晶表示素子の提供。 下記式[1]の基を有する化合物を含有する液晶配向処理剤。 (*は他の構造との結合部位を表す。)
