Abstract
Disclosed are a display panel and a display device. The display panel includes a pixel circuit and a light-emitting element, in the pixel circuit, the driving module includes a drive transistor, and a gate of the drive transistor is connected to a first node; a reset module includes a first sub-transistor and a second sub-transistor, and a connection node between the first sub-transistor and the second sub-transistor is a second node; a compensation module includes a third sub-transistor and a fourth sub-transistor, a connection node between the third sub-transistor and the fourth sub-transistor is a third node; in a first stage, a first double-gate transistor and a second double-gate transistor are both turned off, and the first node, the second node, and the third node satisfy: (V−V)×(V−V)>0.
