Patent ID: 8420463

Claim:
A method for manufacturing a pixel structure, comprising: providing a substrate; forming a patterned first metal layer on the substrate, wherein the patterned first metal layer comprises a gate electrode, a first scan metal layer and a first data metal segment; forming a patterned insulating layer on the patterned first metal layer; forming a patterned semi-conducting layer on the patterned insulating layer; forming a patterned second metal layer comprising a source, a drain, a second scan metal layer and a second data metal layer, wherein the source and the drain are formed on the patterned semi-conducting layer and constitute an active element with the gate electrode, the first data metal segment and the second data metal layer constitute a data line electrically connected to the source, and the first scan metal layer and the second scan metal layer constitute a scan line electrically connected to the gate electrode; forming a patterned passivation layer partially covering a part edge of the drain; and forming a patterned transparent conductive layer comprising a pixel electrode, wherein the pixel electrode is disposed across the patterned passivation layer on the part edge of the drain and electrically connected to the drain, wherein the steps of forming the patterned passivation layer and forming the patterned transparent conductive layer comprise: forming a passivation material layer; forming a patterned photoresist layer on the passivation material layer; etching the passivation material layer to form the patterned passivation layer and a first contact hole exposing a region of the drain, wherein the patterned passivation layer comprises a first passivation layer and a second passivation layer, the first contact hole is formed between the first passivation layer and the second passivation layer, the first passivation layer and the second passivation layer cover sidewalls of the drain, and the region of the drain exposed by the first contact hole is not connected with the sidewalls of the drain; ashing the patterned photoresist layer to expose the second passivation layer and to form a remaining patterned photoresist layer which is on the first passivation layer; forming a transparent conductive layer on the remaining patterned photoresist layer to electrically connect to the drain via the first contact hole; and removing the remaining patterned photoresist layer together with the transparent conductive layer on the remaining patterned photoresist layer to form the patterned transparent conductive layer electrically connected to the drain.
