Abstract
A display panel includes a switching transistor and a light-emitting transistor. The switching transistor includes a first gate electrode, a first source electrode, a first active layer, and a first drain electrode. The light-emitting transistor includes a second gate electrode, a second source electrode, a second active layer, a light-emitting layer, and a second drain electrode. The second gate electrode is the first drain electrode of the switching transistor. The switching transistor and the light-emitting transistor may be on a substrate. The switching transistor, the second source electrode, the second active layer, the light-emitting layer, and the second drain electrode are stacked in a direction perpendicular to the surface of the substrate.
