Abstract: The present invention provides a structure of pixel electrode, which includes a strip-like horizontal main trunk and a strip-like vertical main trunk, the horizontal main trunk and the vertical main trunk centrally and perpendicularly intersecting each other; a plurality of strip-like branches arranged in each of four domains that are formed by being equally divided by the central perpendicular intersection of the horizontal main trunk and the vertical main trunk, the plurality of strip-like branches extending outward from a central point of the perpendicular intersection of the vertical main trunk and the horizontal main trunk, the plurality of strip-like branches being spaced by a plurality of slits; and two centrally symmetric polygonal or sector openings provided in a central zone at the central perpendicular intersection of the horizontal main trunk and the vertical main trunk.
