Pixel structure and repairing method thereof

A pixel structure electrically connected to a scan line and a data line, comprising:

• an active device;
• a pixel electrode, electrically connected with the active device;
• a bottom electrode, disposed under the pixel electrode;
• a plurality of upper electrodes, disposed between the pixel electrode and the bottom electrode and electrically connected with the pixel electrode, wherein the total area of the upper electrodes overlapping with the bottom electrode is A, the overlapping portion of the pixel electrode and each upper electrode comprises a contact region and a reserved region, and the total area of the reserved region is B;
• a first dielectric layer, disposed at least between the bottom electrode and the upper electrodes, wherein the dielectric constant of the first dielectric layer is cl, and the thickness of the first dielectric layer is d1;
• and
• a second dielectric layer, disposed at least between the upper electrodes and the pixel electrode, wherein the dielectric constant of the second dielectric layer is ∈2, the thickness of the second dielectric layer is d2, and 0.5<(∈1·d2·A)/(∈2·d1·B)<1.5.
