Provided are a display panel and display device. The display panel includes a driver circuit comprising a shift register that is N-stage cascaded; wherein the shift register comprises: a third control unit configured to receive a first voltage signal and generate an output signal in response to a signal of a third node, or receive a second voltage signal and generate an output signal in response to a signal of a second node; and a fourth control comprising a first capacitor and a first transistor, wherein a second plate of the first capacitor is connected to a drain of the first transistor, a first plate of the first capacitor and a gate of the first transistor are connected to a same node; and/or a first plate of the first capacitor and a gate of the first transistor receive a same signal.
