Claim 17:
18. A display device, comprising a display panel,
wherein the display panel comprises:
a driver circuit comprising a shift register that is N-stage cascaded, wherein N is a number greater than or equal to 2;
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, wherein the first voltage signal is a low level signal, and the second voltage signal is a high level signal; and
a fourth control unit comprising a first capacitor, a first transistor and a second transistor, wherein a second plate of the first capacitor is connected to a drain of the first transistor, a source of the second transistor is connected to a first node, and a drain of the second transistor is connected to the third node,
wherein a gate of the first transistor receives a second control signal, and the second control signal is a signal of the first node.
