Abstract

A shift register includes a first control circuit configured to, according to one of a second clock signal and a first voltage signal, control a voltage of a second node under control of a voltage of the first node and the second clock signal; and a holding circuit configured to transmit the first voltage signal to an output signal terminal under control of the voltage of the second node. The first control circuit includes a third transistor and a second capacitor. A control electrode of the third transistor is electrically connected to the first node, a first electrode of the third transistor is electrically connected to the first voltage signal terminal, and a second electrode of the third transistor is electrically connected to a third node. First and second ends of the second capacitor are electrically connected to the second clock signal terminal and the third node, respectively.
