A pixel structure including a substrate, a scan line, a data line, an active device, a capacitor electrode and a pixel electrode is described. The substrate has a pixel region. The active device is electrically connected to the scan line and the data line. The capacitor electrode is disposed on the substrate. The pixel electrode is disposed in the pixel region and electrically connected to the active device, wherein the pixel electrode includes a first extending part, a second extending part and branches. The first extending part is disposed above the capacitor electrode and electrically coupling with the capacitor electrode, wherein the capacitor electrode is not completely covered by the first extending part. The second extending part has an extending direction different from that of the first extending part. The branches extend from the first extending part and the second extending part to an edge of the pixel region.
