Abstract

A repairing method for a pixel structure including an active device, a pixel electrode connected with the active device, a bottom electrode disposed under the pixel electrode, upper electrodes disposed between the pixel electrode and the bottom electrode and connected with the pixel electrode, a first dielectric layer disposed between the bottom electrode and the upper electrodes and a second dielectric layer disposed between the upper electrodes and the pixel electrode is provided. The repairing method includes removing a portion of the pixel electrode to electrically isolate the contact region over the upper electrode from the remaining portion of the pixel electrode, wherein a storage capacitor is formed by the reserved region over the upper electrode, the second dielectric layer and the remaining portion of the pixel electrode.
