Original Abstract Submitted
A display device includes a substrate, a first transistor including a first active layer disposed on the substrate and a first gate electrode disposed on the first active layer, and a first gate insulating layer disposed between the first active layer and the first gate electrode. The first active layer includes an oxide semiconductor containing indium (In) at a content range of about 40 at % to about 54 at %, and the first gate insulating layer has an emission amount range of oxygen (O) of about 2.48E+19 Molec./cmto about 2.76E+19 Molec./cm, or an emission amount range of nitrogen monoxide (NO) of about 1.04E+20 Molec./cmto about 1.15E+20 Molec./cmunder heat treatment conditions performed at a temperature range of about 50° C. to about 550° C.
