Claim 9:
10. The display panel according to claim 9, wherein the shift register includes:
a first input circuit electrically connected to the input signal terminal, a pull-up node, and a leakage prevention node; the first input circuit being configured to, during a display period of a frame display phase, transmit an input signal to the pull-up node and the leakage prevention node in response to the input signal received at the input signal terminal;
an output circuit electrically connected to the pull-up node, a first clock signal terminal, and a first output signal terminal; the output circuit being configured to, during the display period of the frame display phase, transmit a first clock signal received at the first clock signal terminal to the first output signal terminal under control of a voltage of the pull-up node; and
a leakage prevention circuit electrically connected to the pull-up node, the first voltage signal terminal and the leakage prevention node; the leakage prevention circuit being configured to transmit a first voltage signal received at the first voltage signal terminal to the leakage prevention node under control of the voltage of the pull-up node, so as to prevent leakage of the pull-up node;
wherein the first input circuit, the output circuit, and the leakage prevention circuit each include at least one device group;
at least one device group used to be electrically connected to the pull-up node in the first input circuit and at least one device group used to be electrically connected to the pull-up node in the output circuit are electrically connected to the pull-up node through a node voltage transmission line; and
at least one device group used to be electrically connected to the leakage prevention node in the first input circuit and at least one device group used to be electrically connected to the leakage prevention node in the leakage prevention circuit are electrically connected to the leakage prevention node through another node voltage transmission line.
