Title (EN) METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY DEVICE
(FR) PROCÉDÉ DE FABRICATION DE DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 液晶表示装置の製造方法
Abstract:
(EN) The present invention provides a method for manufacturing a liquid crystal display device, whereby the occurrence of always-on-pixels is suppressed while reduction of anisotropy is suppressed. This method for manufacturing a liquid crystal display device provided with a pair of substrates and a liquid crystal layer sandwiched between the pair of substrates includes a step (1) for forming a film of an optical alignment film material containing a polymer of a diamine and a carboxylic acid dianhydride having a cyclobutane skeleton on the surface of at least one of the pair of substrates, a step (2) for irradiating the film with polarized light and forming an optical alignment film, and a step (3) for washing the optical alignment film with ozonated water having a concentration of 5 ppm or less for 1 minute or less.
(FR) La présente invention concerne un procédé de fabrication d'un dispositif d'affichage à cristaux liquides, grâce auquel l'apparition de pixels toujours allumés est supprimée tandis que la réduction de l'anisotropie est également supprimée. Ce procédé de fabrication d'un dispositif d'affichage à cristaux liquides pourvu d'une paire de substrats et d'une couche de cristaux liquides prise en sandwich entre la paire de substrats comprend une étape (1) de formation d'un film d'un matériau de film d'alignement optique contenant un polymère d'une diamine et d'un dianhydride d'acide carboxylique ayant un squelette cyclobutane sur la surface d'au moins l'un de la paire de substrats, une étape (2) d'irradiation du film avec une lumière polarisée et de formation d'un film d'alignement optique, et une étape (3) de rinçage du film d'alignement optique avec de l'eau ozonée ayant une concentration de 5 ppm ou moins pendant 1 minute ou moins.
(JA) 本発明は、異方性の低下を抑制しつつ、輝点の発生を抑制する液晶表示装置の製造方法を提供する。本発明の液晶表示装置の製造方法は、一対の基板と、上記一対の基板間に挟持される液晶層とを備える液晶表示装置の製造方法であって、上記一対の基板の少なくとも一方の表面上に、シクロブタン骨格を有するカルボン酸二無水物とジアミンとの重合体を含有する光配向膜材料による膜を形成する工程(1)と、上記膜に対して偏光照射を行い、光配向膜を形成する工程(2)と、上記光配向膜に対して、濃度5ppm以下のオゾン水による洗浄を1分間以下行う工程(3)とを含む。
