Abstract: A display panel includes a light emitting element and a pixel circuit electrically connected to the light emitting element. The pixel circuit includes a transistor. The transistor includes a first gate, an oxide semiconductor member overlapping the first gate, and a second gate overlaps the oxide semiconductor member. The oxide semiconductor member is disposed between the first gate and the second gate and includes a first semiconductor layer and a second semiconductor layer. The second semiconductor layer is disposed between the first semiconductor layer and the second gate in a thickness direction of the oxide semiconductor member. An atomic percent of oxygen of the first semiconductor layer is lower than an atomic percent of oxygen of the second semiconductor layer.
