    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.

    Abstract: Pixel electrodes each include a pixel plane portion expanded along a surface of the substrate, and a pixel wall portion rising up from the pixel plane portion. 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.

    Abstract: The present invention provides a liquid crystal display device including: plural pixels disposed in a matrix shape, each pixel having insulating wall-shaped structures at the boundaries of the pixels and a small wall-shaped structure between the wall-shaped structures; wall electrodes, each having wall-shaped electrodes formed on the side faces of the wall-shaped structures, and planar electrodes that are connected to the wall-shaped electrodes and extend in the planar direction; electrodes, each having a TFT-side electrode covering the small wall-shaped structure and a storage capacitor electrode that is connected to the TFT-side electrode and extends in the planar direction of the substrate; and interlayer insulating films formed between the storage capacitor electrodes and the planar electrodes. And the interlayer insulating films of inorganic films are not formed on the upper and side faces and at the base portions of the wall-shaped structures at the boundaries of the pixels.
