Title (EN) AGENT FOR ALIGNMENT TREATMENT OF LIQUID CRYSTAL AND LIQUID CRYSTAL DISPLAY ELEMENT USING THE SAME
(FR) AGENT POUR TRAITEMENT D'ALIGNEMENT D'UN CRISTAL LIQUIDE ET ÉLÉMENT DE DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES UTILISANT CELUI-CI
(JA) 液晶配向処理剤及びそれを用いた液晶表示素子
Abstract:
(EN) Disclosed is an agent for the alignment treatment of a liquid crystal, which has a highly stabilized pretilt angle. Also disclosed is a liquid crystal display element which has less change in a pretilt angle and also has excellent display reliability. The agent for the alignment treatment of a liquid crystal comprises at least one polymer selected from the group consisting of polyamic acid and polyimide and a crosslinkable compound having at least two oxetane groups represented by the formula [I] in the molecule.
(FR) L'invention concerne un agent pour le traitement d'alignement d'un cristal liquide, qui a un angle de pré-inclinaison extrêmement stabilisé. L'invention concerne également un élément de dispositif d'affichage à cristaux liquides qui a moins de changement dans un angle de pré-inclinaison et a également une excellente fiabilité d'affichage. L'agent pour le traitement d'alignement d'un cristal liquide comprend au moins un polymère choisi dans le groupe consistué par l'acide polyamique et le polyimide et un composé réticulable ayant au moins deux groupes oxétane représentés par la formule [I] dans la molécule.
(JA)  プレチルト角の安定性に優れた液晶配向処理剤を提供すること、及びプレチルト角の変化が少なく表示の信頼性に優れる液晶表示素子を提供すること。  ポリアミド酸及びポリイミドからなる群から選ばれる少なくとも一種類のポリマーと、分子内に下記式{I}で示されるオキセタン基を少なくとも2個有する架橋性化合物とを含有する液晶配向処理剤。
