A display panel and a display device are provided. The display panel includes a driving circuit, and the driving circuit includes N-level shift registers cascaded with each other, where N is greater than or equal to two. A shift register of the N-level shift registers includes: a third control unit, configured to control a signal of a fourth node, the third control unit receives a first voltage signal and a second voltage signal, the first voltage signal is a high-level signal, and the second voltage signal is a low-level signal; and a fourth control unit, configured to generate an output signal, the fourth control unit receives a third voltage signal and a fourth voltage signal, and the third voltage signal is a high-level signal, and the fourth voltage signal is a low-level signal.
