Patent ID: 8274085

Claim:
A pixel structure, comprising: a substrate having a thin film transistor region and a pixel electrode region; a thin film transistor formed at the thin film transistor region and including a drain conduction layer which has an extension section extending to the pixel electrode region, wherein the thin film transistor further includes a channel layer, a gate conduction layer, a source conduction layer, and the drain conduction layer; wherein the channel layer, the gate conduction layer, the drain conduction layer, and the source conduction layer are metallic oxides having indium, gallium, and zinc; and a storage capacitor formed at the pixel electrode region, wherein an electrode layer and the extension section of the drain conduction layer serve as an upper electrode and a lower electrode of the storage capacitor, respectively, and the extension section of the drain conduction layer entirely covers the pixel electrode region, and the capacitance of the storage capacitance is proportional to sizes of the electrode layer and the extension section of the drain conduction layer.
