A display panel and a display device are provided. The display panel includes a base substrate, and one or more first transistors and one or more second transistors over the base substrate. A first transistor of the one or more first transistors includes a first active layer, and the first active layer contains silicon. A second transistor of the one or more second transistors includes a second active layer, and the second active layer contains an oxide semiconductor material. The display panel also includes a shielding layer. The shielding layer is disposed on a side of the first active layer facing away from the base substrate, and is disposed on a side of the second active layer facing away from the base substrate. Along a projection direction perpendicular to the base substrate, the shielding layer fully covers the second active layer.
