Abstract
Provided is a shift register, including a first node control module for controlling a level state of a first node based on an input signal, a first clock signal and a second clock signal. The shift register includes a second node control module for controlling a level state of a second node based on the input signal, the first clock signal, the second clock signal and the level state of the first node. In a phase when the input signal is at high level and the first clock signal is at low level, a third node for controlling a level at the second node is provided with high level, such that in a phase when the input signal is at high level and the second clock signal is at low level, the level at the third node is pulled down so as to provide low level at the second node.
