摘要： 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.

摘要： A display apparatus includes a substrate, a first pixel, a second pixel, a first wire set, and a second wire set. The first pixel and the second pixel overlap the substrate and neighbor each other in a first direction. The first wire set extends in a second direction, includes a first conduction line and a first transmission line, and may transfer a first data signal. The first conduction line is positioned between the substrate and the first transmission line and is connected through the first transmission line to the first pixel. The second wire set extends in the second direction, includes a second conduction line and a second transmission line, and may transfer a second data signal. The second conduction line is positioned between the substrate and the second transmission line and electrically connects the second transmission line to the second pixel.
