A display device includes a first pixel and a second pixel. A light emitting element and a pixel circuit of the second pixel are in a second area. The first pixel includes a silicon transistor and an oxide transistor in the second area. The first pixel includes a connection line that electrically connects one of the silicon transistor and the oxide transistor to a light emitting element in a first area. The connection line is on the same layer as the oxide semiconductor pattern and includes a transparent conductive oxide.

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.
