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.
