Patent ID: 7932519

Claim:
A pixel structure, comprising: a scan line and a data line, arranged intersectedly and electrically insulated from each other; a gate electrode electrically connected to the scan line; a semiconductor layer disposed on the gate electrode; a source electrode, having at least a portion disposed on the semiconductor layer, and connected to the data line; a drain electrode, having at least a portion disposed on the semiconductor layer, the drain electrode comprising: a comb-shaped part, surrounding the source electrode, the comb-shaped part comprising at least two branches, at least one of the branches extending outside the gate electrode to form at least a protrusion part outside the gate electrode; wherein one of the branches extends outside the gate electrode, and the other branch is disposed within the region of the gate electrode completely, so that one protrusion part exists; a connecting part, extending from the comb-shaped part beyond the gate electrode, the protrusion part and the connecting part being respectively disposed on two opposite sides of the gate electrode, wherein the protrusion part aligned with the margin of the gate electrode has a first width, and the connecting part aligned with the margin of the gate electrode has a third width, wherein the first width is substantially equal to the third width; and a pixel electrode, electrically connected to the drain electrode.
