Patent ID: 8687136

Claim:
A repairing method for repairing a pixel structure electrically connected to a scan line and a data line, the pixel structure comprising: an active device; a pixel electrode, electrically connected to the active device, having a plurality of gaps and a plurality of slits therein, wherein the gaps are integrated with the slits; a bottom electrode, disposed under the pixel electrode; a plurality of upper electrodes, disposed between the pixel electrode and the bottom electrode and only connected to the pixel electrode, the pixel electrode connecting the active device and the upper electrodes, wherein each of the upper electrodes comprises a contact region and a reserved region, and each of the gaps is located between the corresponding contact region and the corresponding reserved region of one of the upper electrodes; a first dielectric layer, disposed at least between the bottom electrode and the upper electrodes; and a second dielectric layer, disposed at least between the upper electrodes and the pixel electrode, the second dielectric layer and having a plurality of contact windows for exposing the corresponding upper electrodes in the contact region correspondingly and having no contact window in the reserve region, wherein each of the upper electrodes is only connected to the pixel electrode via the corresponding contact window in the contact region correspondingly; wherein each of the gaps of the pixel electrode is located above the second dielectric layer and between the contact region and the reserved region of one of the upper electrodes correspondingly, and when a short circuit occurs between one of the upper electrodes and the bottom electrode, the repairing method comprising: 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 of the upper electrode, the second dielectric layer and the remaining portion of the pixel electrode.
