摘要： 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.

Common electrodes each include a common plane portion expanded along a surface of the substrate, and a common wall portion rising up from the common plane portion so as to face the pixel wall portion. Each of the compartment areas has the pixel wall portion on one of right and left sides in the lateral direction, and has the common wall portion on the other of the right and left sides. Molecules of the liquid crystal material are tilted up from the pixel wall portions in a direction of the common wall portion by the electric field. The respective pixel wall portions of the adjacent compartment areas are positioned on opposite sides to each other in the lateral direction.
