Abstract: A liquid crystal display device includes a TFT substrate, a CF substrate, and a liquid crystal interposed between the TFT substrate and the CF substrate, and drives the liquid crystal in a horizontal electric field. The TFT substrate includes a recess, and the CF substrate includes a columnar protrusion. The protrusion of the CF substrate is fitted to the recess of the TFT substrate so as to function as a stopper for preventing a positional gap between the TFT substrate and the CF substrate.

Abstract: A liquid crystal display device has a pair of wall electrodes facing each other, which is disposed on pixels on a first substrate, functions as one of pixel electrodes and a common electrode, and takes a posture of standing on the first substrate. Also, the liquid crystal display device has a center electrode that is disposed between the pair of wall electrodes, functions as the other of the pixel electrodes and the common electrode, has a convexity lower in height than the pair of wall electrodes, and makes a width in a direction along which the pair of wall electrodes faces each other gradually smaller toward the second substrate. According to this liquid crystal display device, since a vertical electric field can be prevented from being developed on an upper side of the center electrode, a transmittance of light can be improved.

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.
