In crystallography, a disclination is a line defect in which rotational symmetry is violated. In analogy with dislocations in crystals, the term, disinclination, for liquid crystals first used by Frederick Charles Frank and since then has been modified to its current usage, disclination. It is a defect in the orientation of director whereas a dislocation is a defect in positional order.

A tetragonal ring shape aperture is formed in the common electrode on one substrate and a cross shape aperture is formed at the position corresponding to the center of the tetragonal ring shape aperture in the pixel electrode on the other substrate. A liquid crystal layer between two electrodes are divided to four domains where the directors of the liquid crystal layer have different angles when a voltage is applied to the electrodes. The directors in adjacent domains make a right angle. The tetragonal ring shape aperture is broken at midpoint of each side of the tetragon, and the width of the aperture decreases as goes from the bent point to the edge. Wide viewing angle is obtained by four domains where the directors of the liquid crystal layer indicate different directions, disclination is removed and luminance increases.

Liquid crystal display device
Disclination of an active matrix liquid crystal display device is reduced. Portions of pixel electrodes are formed so as to mutually overlap with a convex portion. If the height of the convex portion is too tall, the amount of light leakage increases due to liquid crystals orienting diagonally with respect to a substrate surface. (See FIG. 1C.) If the height of the convex portion is low, the disclination reduction effect is low. The optimal convex portion height is thus determined.

The MVA-LCD includes an upper substrate, a lower substrate, a plurality of scan lines provided at the lower substrate in a matrix form and a plurality of data lines, as well as a plurality of pixel cells provided in the pixel areas. The MVA-LCD also includes a plurality of the first means provided in each pixel cell in a parallel form with spaces and a plurality of the second means provided at the upper substrate in a parallel and alternating form with respect to the first means. Moreover, the plurality of the first means and the corresponding plurality of the second means are disposed in a parallel and alternating form and are alternated with respect to each other in spaces. Therefore, the disclination lines are reduced, the transmittance is enhanced, and the response time is shortened. Meanwhile, because the first and second means are set in a cyclic disposition of mirror mapping with one pixel cell corresponding to another one, two pixel cells corresponding to the other two, or three pixel cells corresponding to the other three, the phenomenon of color shift is thereby eliminated.
