    • A VA mode LCD obtains a wide viewing angle without forming cutouts or protrusions in the common electrode. A pixel electrode has a cutout; a direction control electrode overlaps the cutout; a first storage electrode overlaps the pixel electrode; and a second storage electrode overlaps the direction control electrode. The pixel electrode has plurality of partitions, each partition has two major edges that are parallel to each other. In the present invention, the electric field generated by the direction control electrode pre-tilts the LC molecules by maintaining the direction control electrode voltage with respect to the common voltage higher than the pixel electrode voltage with respect to the common voltage. The LC molecules in each partition receive horizontal components of electric fields that are substantially perpendicular to the major edges thereby sorting the LC molecules into four tilt directions and thus widening the reference viewing angle according to the tilt directions of the LC molecules.
    • VA模式LCD获得宽视角而不在公共电极中形成切口或突起。 像素电极具有切口; 方向控制电极与切口重叠; 第一存储电极与像素电极重叠; 并且第二存储电极与方向控制电极重叠。 像素电极具有多个隔板,每个隔板具有彼此平行的两个主边缘。 在本发明中,由方向控制电极产生的电场通过相对于公共电压相对于高于像素电极电压的公共电压维持方向控制电极来预先倾斜LC分子。 每个分区中的LC分子接收基本上垂直于主边缘的电场的水平分量,从而将LC分子分选成四个倾斜方向,从而根据LC分子的倾斜方向扩大参考视角。
