Title (EN) LIQUID CRYSTAL ORIENTATION AGENT FOR PHOTO-ORIENTATION TREATMENT METHOD AND LIQUID CRYSTAL ORIENTATION FILM USING SAME
(FR) AGENT D'ORIENTATION DE CRISTAUX LIQUIDES POUR UN PROCÉDÉ DE TRAITEMENT DE PHOTO-ORIENTATION ET FILM D'ORIENTATION DE CRISTAUX LIQUIDES L'UTILISANT
(JA) 光配向処理法用の液晶配向剤、及びそれを用いた液晶配向膜
Abstract:
(EN) Provided are a liquid crystal orientation agent ideal for photo-orientation treatment and a liquid crystal orientation film obtained from the liquid crystal orientation agent with which it is possible to inhibit the after-image of alternating current operation that is generated in an IPS-type or FFS-type liquid crystal display element. The liquid crystal orientation agent for photo-orientation comprises a polyamic acid obtained by polycondensation of a tetracarboxylic dianhydride having a predetermined structure and a cyclobutane skeleton and a diamine compound comprising a diamine compound of high linearity, such as p-phenylenediamine (component (A)); an imidazole having C3-10 alkyl groups or alkenyl groups (component (B)); and an organic solvent.
(FR) L'invention concerne un agent d'orientation de cristaux liquides idéal pour un traitement de photo-orientation et un film d'orientation de cristaux liquides obtenu à partir de l'agent d'orientation de cristaux liquides avec lequel il est possible d'inhiber l'image-après d'un fonctionnement en courant alternatif laquelle est générée dans un élément d'affichage à cristaux liquides de type à commutation en plan (IPS) ou de type à commutation de champs de franges (FFS). L'agent d'orientation de cristaux liquides pour une photo-orientation comprend un acide polyamique obtenu par polycondensation d'un dianhydride tétracarboxylique ayant une structure prédéterminée et un squelette cyclobutane et d'un composé diamine comprenant un composé diamine de linéarité élevée, par exemple la p-phénylènediamine (composant (A)); un imidazole ayant des groupes alkyles ou groupes alcényles en C3-10 (composant (B)); et un solvant organique.
(JA)  IPS駆動方式やFFS駆動方式の液晶表示素子において発生する交流駆動による残像を抑制することができる、光配向処理法用に適した液晶配向剤、及び該液晶配向剤から得られる液晶配向膜を提供する。 シクロブタン骨格を有する特定構造のテトラカルボン酸二無水物とp-フェニレンジアミンに代表される直線性の高いジアミン化合物を有するジアミン化合物との重縮合反応から得られるポリアミック酸((A)成分)と、炭素数3~10のアルキル基、又はアルケニル基を有するイミダゾール誘導体((B)成分)と、有機溶剤とを含有する光配向処理法用の液晶配向剤。
