Abstract:
1. A pixel structure electrically connected to a scan line and a data line, 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 the total area of the upper electrodes overlapping with the bottom electrode is A, the overlapping portion of the pixel electrode and each of the upper electrodes comprises a contact region and a reserved region, 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 ∈ a second dielectric layer, disposed at least between the upper electrodes and the pixel electrode, the second dielectric layer having a plurality of contact windows for exposing the 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 contact window in the contact region correspondingly, the dielectric constant of the second dielectric layer is ∈ 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.
