    • A pixel electrode includes strip-like horizontal and vertical main trucks, which perpendicularly intersect at an intersection point coincident with centers of the main trucks. Four pixel domains are formed by being equally divided by the main trunks. Each pixel domain includes a plurality of flat-laid strip-like branches extending outward at the same included angle with respect to the horizontal main trunk. A spacing distance is formed between adjacent branches. Connection portions between the branches and the horizontal or vertical main trunk have a width less than width of body sections of the branches in order to overcome the technical problem of prior art that liquid crystals at locations close to left and right sides of the vertical main trunk at the center of pixel compress each other and form disclination lines and thus affecting the efficiency of liquid crystal, so as to improve efficiency of liquid crystal.
    • 像素电极包括带状水平和垂直主卡车,其在与主卡车的中心重合的交叉点处垂直相交。 四个像素域通过被主干线等分而形成。 每个像素区域包括多个平行的条状分支,其以相对于水平主干线的相同的夹角向外延伸。 在相邻分支之间形成间隔距离。 为了克服现有技术的技术问题,分支和水平或垂直主干之间的连接部分具有小于分支体部分宽度的宽度,在靠近垂直主干的左侧和右侧的位置处的液晶 在像素的中心彼此压缩并形成旋错线,从而影响液晶的效率,从而提高液晶的效率。
