Abstract: A pixel structure includes a switching element, a first electrode, and a second electrode. The first electrode includes two first main portions parallel to an extension direction of the data line, a girder portion coupled between the two first main portions, and two connection portions coupled between the two first main portions. The girder portion and the two connection portions are parallel to an extension direction of the scan line, and the girder portion is disposed between the two connection portions. The second electrode includes a second main portion parallel to the extension direction of the data line, multiple branch portions symmetrically coupled with the second main portion, and two extension portions parallel to the extension direction of the data line. Each of the two extension portions is coupled with two of the multiple branch portions.
