A pixel structure including a scan line, a data line, an active device, a shielding electrode, and a pixel electrode is provided on a substrate. The data line includes an upper conductive wire and a bottom conductive wire. The upper conductive wire is disposed over and across the scan line. The bottom conductive wire is electrically connected to the upper conductive wire. The active device is electrically connected to the scan line and the upper conductive wire. The shielding electrode is disposed over the bottom conductive wire. The pixel electrode disposed over the shielding electrode is electrically connected to the active device. In addition, parts of the pixel electrode and parts of the shielding electrode form a storage capacitor.
