Title (EN) ORIENTED FILM, POLYMER, AND LIQUID-CRYSTAL DISPLAY DEVICE
(FR) FILM ORIENTÉ, POLYMÈRE, ET DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 配向膜、重合体、及び、液晶表示装置
Abstract:
(EN) The purpose of the present invention is to provide a liquid-crystal display device in which burn-in and discoloration are satisfactorily suppressed. The present invention is an oriented film that contains a polymer, wherein the polymer is polysiloxane or polyvinyl, and, in addition, the polymer has a silsesquioxane group. The present invention is also a polymer that has a silsesquioxane group and that is used in the aforementioned oriented film. The present invention is also a liquid-crystal display device that includes: the aforementioned oriented film; a pair of substrates; and a liquid crystal layer that is held between the pair of substrates, wherein the oriented film is disposed between the liquid crystal layer and at least one of the pair of substrates.
(FR) Le but de la présente invention est de produire un dispositif d'affichage à cristaux liquides dans lequel il est possible de supprimer de manière satisfaisante le déverminage et la décoloration. La présente invention est un film orienté qui contient un polymère, le polymère étant un polysiloxane ou un polyvinyle et possédant de plus un groupe silsesquioxane. La présente invention concerne également un polymère qui possède un groupe silsesquioxane et qui est utilisé dans le film orienté précité. La présente invention concerne également un dispositif d'affichage à cristaux liquides qui comprend ledit film orienté; une paire de substrats; et une couche de cristaux liquides qui est maintenue entre la paire de substrats, le film orienté étant disposé entre la couche de cristaux liquides et au moins l'un des deux substrats.
(JA) 本発明は、焼き付き、シミが充分に抑制された液晶表示装置を提供することを目的とする。本発明は、重合体を含み、該重合体は、ポリシロキサン又はポリビニルであり、更に、シルセスキオキサン基を有する配向膜である。本発明は、上記配向膜に用いられる、シルセスキオキサン基を有する重合体でもある。本発明は、上記配向膜と、一対の基板と、該一対の基板間に挟持された液晶層とを有し、該配向膜は、該一対の基板の少なくとも一方と該液晶層との間に配置されている液晶表示装置でもある。
