Abstract
An orientation controller which divides a pixel into a plurality of different priority alignment regions and an additional orientation controller are provided in a pixel. The additional orientation controller is provided at least at an end of a pixel of a long-side alignment region formed along the long side of the pixel among the divided alignment regions, for example, around a center position of the long side of the pixel. The additional orientation controller can be realized, for example, by forming a cutout pattern in a side of a first electrode (pixel electrode) forming a part of the pixel. Because the alignment direction is also controlled by the additional orientation controller, the alignment of liquid crystal in this region is stabilized.
