Patent ID: 7998803

Claim:
A method for manufacturing a pixel structure, comprising: providing a substrate having a pixel region; forming a patterned first metal layer on the substrate; forming an insulating layer and a semiconductor layer, wherein the insulating layer is disposed on the patterned first metal layer within the pixel region, and the semiconductor layer is disposed on the insulating layer; forming an oxidized metal layer on the substrate, wherein the oxidized metal layer covers the patterned first metal layer, the semiconductor layer and the insulating layer; forming a second metal layer on the oxidized metal layer; patterning the oxidized metal layer and the second metal layer by a halftone mask or a gray-tone mask to form a thin film transistor (TFT), a data line and a pixel electrode, wherein the data line and the pixel electrode are coupled to the TFT; and reflowing a photoresist material to form a passivation layer, wherein the passivation layer covers the TFT and the data line.
