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: In an LCD device having wall electrodes, four kinds of pixels are used that impart different alignment properties to the liquid crystal molecules. Specifically, the LC molecules are aligned such that: the LC molecules in first pixels twist clockwise and rise in a plus direction; the LC molecules in second pixels twist clockwise and rise in a minus direction; the LC molecules in third pixels twist counterclockwise and rise in the plus direction; and the LC molecules in fourth pixels twist counterclockwise and rise in the minus direction. The pixels of the same type are arranged in rows such that their long sides are adjacent to one another.
