Patent ID: 8785922

Claim:
A thin film transistor (TFT) comprising: a substrate; a gate electrode formed over the substrate; an active layer insulated from the gate electrode by using a gate insulation film; an etch stop layer which is formed over the active layer and comprises a first hole and a second hole for exposing the active layer; a first electrode comprising a first part and a second part, wherein the first part is formed over the etch stop layer, and the second part is received in the first hole, contacts the active layer directly, and connects the first part to the active layer; and a second electrode comprising a first part and a second part, wherein the first part is formed over the etch stop layer, and the second part is received in the second hole, contacts the active layer directly, and connects the first part to the active layer, wherein at least one portion of the first part of the first electrode and the second part of the first electrode overlap with the gate electrode, at least one portion of the first part of the second electrode overlaps with the gate electrode, and the second part of the second electrode does not overlap with and is separated from the gate electrode.
