Title (EN) POLYMER FOR PHOTOALIGNMENT FILM, POLYMER SOLUTION, PHOTOALIGNMENT FILM, OPTICALLY ANISOTROPIC BODY, AND LIQUID CRYSTAL DISPLAY ELEMENT
(FR) POLYMÈRE POUR FILM DE PHOTO-ALIGNEMENT, SOLUTION POLYMÈRE, FILM DE PHOTO-ALIGNEMENT, CORPS ANISOTROPE OPTIQUE ET ÉLÉMENT D’AFFICHAGE À CRISTAUX LIQUIDES
(JA) 光配向膜用ポリマー、ポリマー溶液、光配向膜、光学異方体、及び液晶表示素子
Abstract: front page image
(EN)The present invention addresses the problem of providing: a polymer for a photoalignment film, said polymer being capable of forming a photoalignment film that has an excellent alignment regulating force; a photoalignment film that is formed using the polymer for a photoalignment film; and an optically anisotropic body and liquid crystal display element that have said photoalignment film. This polymer for a photoalignment film makes it possible to form a photoalignment film that has an excellent alignment regulating force. Since this photoalignment film has excellent liquid crystal alignment properties, AC burn-in in a liquid crystal display element provided with the photoalignment film can be reduced.
(FR)L’invention concerne: un polymère pour film de photo-alignement permettant de former un film de photo-alignement présentant d'excellentes caractéristiques de force de restriction de l’alignement; un film de photo-alignement formé au moyen de ce polymère pour film de photo-alignement; un corps anisotrope optique et un élément d'affichage à cristaux liquides possédant ce film de photo-alignement. Par la mise en oeuvre de ce polymère pour film de photo-alignement, il est possible de former un film de photo-alignement présentant d'excellentes caractéristiques de force de restriction de l’alignement. Afin d’obtenir un excellent alignement des cristaux liquides, ce film de photo-alignement permet de réduire le déverminage AC de l’élément d'affichage à cristaux liquide qui le possède.
(JA)本発明は、優れた配向規制力を有する光配向膜を形成可能な光配向膜用ポリマー、前記光配向膜用ポリマーによって形成された光配向膜、前記光配向膜を有する光学異方体および液晶表示素子の提供を課題とする。本発明にかかる光配向膜用ポリマーによれば、優れた配向規制力を有する光配向膜を形成することができる。本発明の光配向膜は優れた液晶配向性を有するため、これを備えた液晶表示素子のAC焼き付きを低減することができる。
