Patent ID: 8330162

Claim:
A pixel structure, comprising: a substrate; a patterned first conductive layer disposed on the substrate, comprising: at least a gate line substantially disposed along a first direction; and at least a gate electrode extended from the gate line; a gate dielectric layer disposed on the patterned first conductive layer; a patterned semiconductor layer disposed on a part of the gate dielectric layer, comprising: a thin film transistor channel layer; and an islanding semiconductor layer not overlapping with the patterned first conductive layer disposed substantially parallel to the first direction; a patterned second conductive layer disposed on a part of the patterned semiconductor layer, comprising: a source line; a source electrode and a drain electrode covering parts of the thin film transistor channel layer; and a drain extension portion covering a part of the islanding semiconductor layer, the drain extension portion and the drain electrode forming a continuous structure; a protection layer disposed on the substrate, the protection layer covering the patterned second conductive layer, a part of the patterned semiconductor layer, and a part of the gate dielectric layer; and a patterned third conductive layer disposed on the protection layer and electrically connected to the drain electrode, wherein the patterned third conductive layer has an edge disposed parallel and adjacent to a part of the gate line, and the islanding semiconductor layer is disposed under a part of the edge.
