Display device

A display device, comprising:

• pixels connected to scan lines and data lines intersecting the scan lines, wherein each of the pixels 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 a respective data line of the data lines, and a switching transistor configured to apply the data voltage of the respective data line to the driving transistor according to a scan signal applied to a respective scan line of the scan lines,
• the driving transistor and the switching transistor include an active layer including an oxide semiconductor containing indium (In), and
• a content of the indium in the oxide semiconductor of the active layer is 70 at % or more.
