    Abstract: A display apparatus includes a substrate including a display area and a peripheral area outside the display area, a pixel circuit disposed on the substrate in the display area, where the pixel circuit includes a driving thin film transistor and a switching thin film transistor, and a display element connected to the pixel circuit. The driving thin film transistor includes a driving semiconductor layer having a single layer structure, the switching thin film transistor includes a switching semiconductor layer in which a first layer, a second layer, and a third layer, which are oxide semiconductors, are sequentially stacked one on another, and a conductivity of the second layer of the switching semiconductor layer is greater than respective conductivities of the first layer and the third layer of the switching semiconductor layer.
