Claim:
1. A thin film transistor (TFT) for a display device, the TFT comprising: a substrate; an oxide semiconductor formed over the substrate; source and drain electrodes electrically connected to the oxide semiconductor at both sides of the oxide semiconductor; a first insulating layer formed over the oxide semiconductor; a gate electrode formed over the first insulating layer and at least partially overlapping the oxide semiconductor; a second insulating layer formed over the gate electrode; a first conductive layer formed over the source and drain electrodes; and a second conductive layer formed over the first conductive layer, wherein the second insulating layer is integrally formed with the first conductive layer in an inseparable body, wherein the second insulating layer covers sides of the gate electrode and the first insulating layer, wherein the second insulating layer contacts the source and drain electrodes, and wherein edges of the second insulating layer are disposed between the first conductive layer and the first insulating layer.
