Patent ID: 8501552

Claim:
A method of fabricating a pixel structure, comprising: providing a substrate; forming a scan line and a gate electrode on the substrate; forming an insulating layer and a semiconductor layer sequentially on the substrate, the scan line and the gate electrode; forming a metal layer on the semiconductor layer; forming a first patterned photoresist layer on the metal layer, wherein the first patterned photoresist layer has a planar top side; removing the metal layer not covered by the first patterned photoresist layer to form an electrode pattern and a data line, and removing the semiconductor layer not covered by the first patterned photoresist layer to form a channel, wherein the data line does not overlap the scan line; performing an ashing process upon the first patterned photoresist layer for reducing a thickness of the first patterned photoresist layer to form a second patterned photoresist layer, wherein the second patterned photoresist layer partially exposes the electrode pattern, and a top side of the second patterned photoresist layer and a top side of the electrode pattern are coplanar; removing the electrode pattern not covered by the second patterned photoresist layer to form a source electrode and a drain electrode; removing the second patterned photoresist layer; forming at least one passivation layer on the source electrode, the drain electrode and the data line, wherein the passivation layer has a first contact hole partially exposing the drain electrode, and a plurality of second contact holes partially exposing the data line or the scan line; and forming a patterned transparent conductive layer on the passivation layer, wherein the patterned transparent conductive layer comprises a pixel electrode electrically connected to the drain electrode through the first contact hole and a connecting electrode electrically connected to the data line or the scan line through the second contact holes, wherein the data line comprises a first data line segment and a second data line segment separated from each other and respectively disposed at two sides of the scan line, the second contact holes of the passivation layer respectively partially expose the first data line segment and the second data line segment, and the connecting electrode is electrically connected to the first data line segment and the second data line segment through the second contact holes.
