Patent ID: 7413922

Claim:
A method of fabricating a pixel structure, comprising: providing a substrate where a color filter layer is already formed thereon, and the color filter layer is covered by a leveling layer; forming a first metal layer on the leveling layer; performing a first photomask process for patterning the first metal layer, so as to define a source and a drain; sequentially forming a channel material layer, a gate insulating layer, and a second metal layer above the substrate for covering the source and the drain; performing a second photomask process for patterning the second metal layer, the gate insulating layer, and the channel material layer, so as to define a gate and a channel layer; forming a passivation layer above the substrate for covering the gate; performing a third photomask process for patterning the passivation layer, so as to expose a portion of the drain; forming a transparent conductive layer above the substrate, wherein the transparent conductive layer is electrically connected to the exposed drain; and performing a fourth photomask process to define a pixel electrode.
