摘要： A display device includes a first transistor, a pixel electrode electrically connected to the first transistor, and a second transistor electrically connected to the first transistor. A nitrogen content per unit area of an active layer of the second transistor is greater than a nitrogen content per unit area of an active layer of the first transistor.
