Abstract

Provided are a display panel and a display device. The display panel includes a base substrate; a first transistor, a second transistor and a third transistor, where the first transistor, the second transistor and the third transistor are formed on the base substrate, the first transistor includes a first active layer, a first gate, a first source, and a first drain, the first active layer contains silicon, the second transistor includes a second active layer, a second gate, a second source, and a second drain, and the second active layer contains an oxide semiconductor; and a first insulating layer and a second insulating layer, where the first insulating layer is disposed on one side of the second active layer facing away from the base substrate and between the second gate and the second active layer.
