Patent ID: 8305508

Claim:
A method for fabricating a pixel structure, comprising: forming a first patterned metal layer on a substrate, the first patterned metal layer comprising a gate electrode, a gate extension electrode, a first data line segment and a second data line segment connected with the first data line segment; forming a gate insulating layer on the substrate and the first patterned metal layer; forming a semiconductor channel layer on the gate insulating layer above the gate electrode; forming a second patterned metal layer on the gate insulating layer and the semiconductor channel layer, the second patterned metal layer comprising a source electrode, a drain electrode, a gate line and a common electrode, wherein the source electrode and the drain electrode are correspondingly formed on the semiconductor channel layer above two sides of the gate electrode, and the common electrode is disposed above the first data line segment; forming a passivation layer on the gate insulating layer and the second patterned metal layer; forming a plurality of first contact holes and a plurality of second contact holes at the same time, wherein the first contact holes separately expose a portion of the gate extension electrode and a portion of the second data line segment of the first patterned metal layer, and the second contact holes separately expose a portion of the gate line, a portion of the source electrode and a portion of the drain electrode of the second patterned metal layer; and forming a conducting layer covering the first contact holes and the second contact holes, such that the gate line of the second patterned metal layer is electrically connected by the conducting layer through the first contact hole and the second contact hole to the gate extension electrode of the first patterned metal layer, and the source electrode of the second patterned metal layer is electrically connected by the conducting layer through the first contact hole and the second contact hole to the second data line segment of the first patterned metal layer.
