Abstract
A display panel and a display device are provided in the present disclosure. The display panel includes a base substrate, a first transistor, a second transistor, a pixel circuit, and a drive circuit. A first active layer of the first transistor includes silicon; and a second active layer of the second transistor includes an oxide semiconductor. A length of a channel region of the first transistor is LL a distance between a first gate electrode and the first active layer is D1, and a first area S1=L1×D1; and a length of a channel region of the second transistor is L2, a distance between a second gate electrode and the second active layer is D2, and a second area S2=L2×D2, where S1<S2. The second transistor is included in the drive circuit, and the first transistor is included in one of the pixel circuit and the drive circuit.
