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 translation: 在一个基板上的公共电极上形成四角环形孔，并且在与另一个基板上的像素电极中的四边形环形孔的中心对应的位置处形成十字形孔。 两个电极之间的液晶层被分成四个畴，其中当向电极施加电压时，液晶层的导向器具有不同的角度。 相邻领域的董事是直角的。 四边形环形孔在四边形的每一侧的中点断开，并且孔的宽度从弯曲点向边缘减小。 通过四个畴获得宽视角，其中液晶层的指向物指示不同的方向，旋错和亮度增加。
