Abstract: Disclosed are a display panel and a display device. The pixel circuit in the display panel includes a control circuit, a drive circuit, and a regulating circuit. The control circuit controls the potential of the coupled control node based on the gate drive signal provided by the gate line and the data signal provided by the data line. The drive circuit drives the light-emitting element to emit light based on the potential of the control node and the drive power signal provided by the drive power line. The regulating circuit adjusts the potential of the control node through the coupling effect based on the drive power signal and the initial power signal provided by the initial power line.
