Abstract: A method of manufacturing a thin film transistor and a method of manufacturing a display substrate having the same are disclosed. In one aspect, the method of manufacturing a thin film transistor comprises forming an oxide semiconductor layer over a substrate, plasma-treating the oxide semiconductor layer with a plasma generated from a nitrogen gas or a nitric oxide gas so as to decrease defects in the oxide semiconductor layer, and annealing the plasma-treated oxide semiconductor layer to form a channel layer.

Abstract: A thin film transistor is disposed on a substrate. A via insulating layer having a via hole covers the thin film transistor. A pixel electrode is disposed on the via insulating layer and electrically connected to the thin film transistor through the via hole. A first protection layer surrounds the pixel electrode. A pixel-defining layer covers an edge region of the pixel electrode and at least a portion of the first protection layer. The pixel-defining layer includes an opening through which an upper surface of the pixel electrode is exposed. An opposite electrode faces the pixel electrode. An intermediate layer is disposed between the pixel electrode and the opposite electrode.
