Abstract: 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.

Abstract: Two electrodes parallel to each other are formed on one of two substrates, homeotropic alignment films are formed on the substrates and a liquid crystal material having positive dielectric anisotropy is injected between the substrates. When a voltage is appled to the two electrodes, a parabolic electric field between the electrodes drives the liquid crystal molecules. Since the generated electric field is symmetrical with respect to the boundary-plane equal distance from each of the two electrodes, the liquid crystal molecules are symmetrically aligned with respect to the boundary-plane, and the optical characteristic is compensated in both regions divided by the boundary-plane, thereby obtaining a wide viewing angle. The electric field does not exert influences on the liquid crystal molecules on the boundary-plane since the electric field on the boundary-plane is parallel to the substrates and perpendicular to the two electrodes and thus, it is perpendicular to the liquid crystal molecules. Here, the polarization of the light is changed while passing through the liquid crystal layer and as a result, only a part of the light passes through the polarizing plate The transmittance of the light can be varied by controlling the magnitude of voltage applied to the two electrodes. The alignment direction of the liquid crystal molecules is changed in both regions of a bent portion of the electrodes by forming the electrodes in the saw shape in a pixel or in by pixel, and the retardation of the light is compensated, thereby obtaining a wider viewing angle.

Abstract: Saw-shaped protrusions, which are parallel to each other, are formed on the common electrode and the pixel electrode in two substrates. Protrusions in two substrates are arranged alternately and the bent portions of the saw-shaped protrusions are placed on the line transverse passing through the center of a pixel. Branches extend from the convex point of one saw-shaped protrusion toward the apex to the other saw-shaped protrusion, and another branch extend from the point where the protrusion meets the boundary of the pixel electrode toward the point where the boundary of the pixel electrode and the saw-shaped protrusion make an acute angle. A liquid crystal layer between two electrodes are divided to four regions where the directors of the liquid crystal layer have different angles when a voltage is applied to the electrodes, and then, wide viewing angle is obtained. In most regions, protrusions are formed straight and the protrusions have only obtuse angles at the bent points. Therefore, fast response time is shortened, disclination is removed and luminance increases.

Abstract: A thin film transistor array substrate is provided with a gate line assembly, a data line assembly, and thin film transistors. The data line assembly crosses over the gate line assembly while defining pixel regions. A pixel electrode is formed at each pixel region. A color filter substrate is provided with a black matrix, and color filters of red, green and blue are formed at the black matrix at the pixel regions. An overcoat layer covers the color filters, and a common electrode is formed on the overcoat layer with an opening pattern. The thin film transistor array substrate, and the color filter substrates face each other, and a liquid crystal material is injected between the thin film transistor array substrate, and the color filter substrate. The blue color filter has a thickness smaller than the red color filter or the green color filter such that the liquid crystal cell gap at the blue color filter is larger than the liquid crystal cell gap at the red or green color filter.
