Abstract
Pixel electrodes and a common electrode are formed on a first panel. A wall is formed on the first panel. The wall includes a large insulating wall that is made of an insulating material and projects toward a second panel, and a wall electrode part that covers a side wall of the large insulating wall and functions as the pixel electrode or the common electrode. The wall includes a side surface on which an alignment film that defines an alignment of liquid crystal molecules of a liquid crystal layer is formed. The side wall of the wall is inclined with respect to a direction perpendicular to the first panel and the second panel. With this configuration, in a liquid crystal display device having the wall electrode, light leakage at the time of displaying a black image can be reduced.
