Abstract
Provided are a display panel and a display device. The display panel includes a pixel driving circuit and a reset control circuit. The pixel driving circuit includes a light-emitting element, a first reset module, a first control module, a data write module, a driving transistor, a second reset module and a second control module. In the initial reset stage of the pixel driving circuit, the reset control circuit is configured to control the first reset module to turn on and apply a reset voltage of the reset voltage terminal to the first electrode of the light-emitting element, and the first scan signal terminal is configured to control the second reset module to turn on and apply the reset voltage to the gate of the driving transistor.
