发明名称 Liquid crystal display device that controls disinclination caused by a lateral electric field
摘要 The invention provides a liquid crystal device capable of obtaining a bright image with a high display quality by controlling disclination caused by a lateral electric field developed across a space between pixels, or the like. With a liquid crystal display of the present invention, where d is a layer thickness of a liquid crystal layer, then alignment treatment in a direction corresponding to a twist angle is applied onto each substrate in such a manner that, in a state that no voltage is applied, a direction of the long axis of a liquid crystal molecule positioned (¼)d high from the surface of a bottom substrate is oriented to a direction that is perpendicular to an extending direction of a space between the electrodes where a twist angle theta of the liquid crystal layer is in a range of theta<=90°, and to a direction that is in parallel to the extending direction of the space between the electrodes where the twist angle theta of the liquid crystal layer is in a range of 180°<=theta<=270°.
