The present disclosure provides a shift register. The shift register includes: a first node control module for controlling level at the first node; a second node control module for controlling level at a second node; and an output control module for controlling the output terminal to output high or low level. The first node control module includes an input unit configured to write the input signal into the third node and a protection unit configured to control a level at a fourth node based on a level at the third node and control writing of the level at the fourth node into the first node based on the second clock signal. The technical solution of the present disclosure can prevent the transistor for providing the third node with inputting signal from being broken down.
