METHOD FOR PRODUCING LIQUID CRYSTAL PANEL
(FR)
PROCÉDÉ DE PRODUCTION DE PANNEAU À CRISTAUX LIQUIDES
(JA)
液晶パネルの製造方法
Abstract:
(EN)
The present invention provides a method for producing a liquid crystal panel, which is capable of imparting a liquid crystal molecule with a pretilt angle with use of a horizontal photo-alignment film by a simple process, and which is not susceptible to the occurrence of disclination. A method for producing a liquid crystal panel according to the present invention is a method for producing a liquid crystal panel having a pair of substrates, a liquid crystal layer held between the pair of substrates and a horizontal photo-alignment film arranged between at least one of the pair of substrates and the liquid crystal layer, and comprises a step for forming, on at least one of the pair of substrates, a film that contains a polymer having a specific structure and a step for irradiating the film with S polarized light from a direction inclined to the normal direction of the substrate surface, thereby forming a horizontal photo-alignment film that is obtained by aligning the film. The horizontal photo-alignment film has properties of aligning liquid crystal molecules to be perpendicular to the polarization direction of the light irradiated from the normal direction of the substrate.
(FR)
La présente invention concerne un procédé de production d'un panneau à cristaux liquides, qui est apte à conférer à une molécule de cristaux liquides un angle de pré-inclinaison à l'aide d'un film de photo-alignement horizontal par un processus simple, et qui n'est pas sensible à l'apparition d'une désinclinaison. Le procédé de production d'un panneau à cristaux liquides selon la présente invention est un procédé de production d'un panneau à cristaux liquides ayant une paire de substrats, une couche de cristaux liquides maintenue entre la paire de substrats et un film de photo-alignement horizontal agencé entre au moins l'un de la paire de substrats et de la couche de cristaux liquides, et comprend une étape consistant à former, sur au moins l'un de la paire de substrats, un film qui contient un polymère ayant une structure spécifique et une étape consistant à éclairer le film avec une lumière polarisée S à partir d'une direction inclinée par rapport à la direction normale de la surface du substrat, ce qui forme un film de photo-alignement horizontal qui est obtenu en alignant le film. Le film de photo-alignement horizontal a des propriétés permettant d'aligner des molécules de cristaux liquides de façon perpendiculaire à la direction de polarisation de la lumière éclairée à partir de la direction normale du substrat.
