Pixel structure

A pixel structure, comprising:

• a substrate, a lower common electrode and a gate line formed on the substrate, a first passivation layer formed on the lower common electrode and the substrate, a data line and a pixel electrode formed on the first passivation layer, a second passivation layer formed on the pixel electrode, the data line, and the first passivation layer, and an upper common electrode formed on the second passivation layer, the first passivation layer comprising a first via hole, the second passivation layer comprising a second via hole, the lower common electrode being connected through the first and second via holes to the upper common electrode, the lower common electrode and the pixel electrode partially overlapping each other to form a first capacitor, the upper common electrode and the pixel electrode partially overlapping each other to form a second capacitor, the first and second capacitors constituting a storage capacitor of the pixel structure;
• wherein the lower common electrode comprises a raised structure corresponding to the first and second via holes, the raised structure extending through the first and second via holes to connect to the upper common electrode, the raised structure further extending through a gate line of another pixel structure that is located under the pixel structure and insulated from the gate line of said another pixel structure;
• wherein the raised structure is electrically connected through a connection layer to the lower common electrode, the connection layer, the lower common electrode, and the raised structure being formed simultaneously;
• wherein the raised structure comprises a circular pillar and the first and second via holes are both circular in shape;
• and
• wherein the upper common electrode comprises a portion overlapping the data line, the data line and the upper common electrode partially overlapping each other to form a parasitic capacitor.
