Abstract
A display device includes a pixel connected to a scan line, and a data line crossing the scan line, wherein the pixel includes a light-emitting element, a driving transistor configured to control a driving current supplied to the light-emitting element according to a data voltage applied from the data line, and a first switching transistor configured to apply the data voltage of the data line to the driving transistor according to a scan signal that is applied to the scan line. The driving transistor includes a first active layer including an oxide semiconductor, and a first oxide layer disposed on the first active layer and including an oxide semiconductor. The first switching transistor includes a second active layer including an oxide semiconductor, and the first oxide layer is not disposed on the second active layer.
