Abstract:
(EN) The present invention provides a liquid crystal display device whereby ghosting caused by application of AC voltage can be suppressed, and a method for manufacturing a liquid crystal display device whereby such a liquid crystal display device can be manufactured. The present invention is a liquid crystal display device provided with a liquid crystal layer containing a liquid crystal material having positive dielectric anisotropy, a seal material disposed so as to surround the liquid crystal layer in plan view, a pair of substrates sandwiching the liquid crystal layer, and an optical alignment film provided to a surface of at least one of the pair of substrates, the optical alignment film containing a polyamic acid and/or a polyimide and causing a liquid crystal compound in the liquid crystal material to align in the horizontal direction with respect to the substrate surface, at least one of the pair of substrates including a pixel electrode and a shared electrode, the pixel electrode and/or the shared electrode including a linear part, and the inclination angle of the linear part with respect to the initial alignment direction of the liquid crystal compound being 7° or greater in plan view.
(FR) La présente invention concerne un dispositif d'affichage à cristaux liquides grâce auquel un effet fantôme provoqué par l'application d'une tension alternative peut être supprimé, et un procédé de fabrication d'un dispositif d'affichage à cristaux liquides grâce auquel un tel dispositif d'affichage à cristaux liquides peut être fabriqué. La présente invention concerne un dispositif d'affichage à cristaux liquides comprenant une couche de cristaux liquides contenant un matériau à cristaux liquides ayant une anisotropie diélectrique positive, un matériau d'étanchéité disposé de façon à entourer la couche de cristaux liquides dans une vue en plan, une paire de substrats prenant en sandwich la couche de cristaux liquides, et un film d'alignement optique disposé sur une surface d'au moins l'un des deux substrats, le film d'alignement optique contenant un acide polyamique et/ou un polyimide et amenant un composé à cristaux liquides dans le matériau à cristaux liquides à s'aligner dans la direction horizontale par rapport à la surface du substrat, au moins l'un des deux substrats comprenant une électrode de pixel et une électrode partagée, l'électrode de pixel et/ou l'électrode partagée comprenant une partie linéaire, et l'angle d'inclinaison de la partie linéaire par rapport à la direction d'alignement initial du composé de cristaux liquides étant supérieur ou égal à 7° dans une vue en plan.
