Abstract
A shift register including a plurality of stages, each of them including a first node, a second node, and a third node being in a high-impedance state when the first node is in a high-impedance state. The shift register includes an input circuit unit inputting a driving voltage to the first node in response to an output signal of a previous stage, a driving circuit unit generating an output signal according to a voltage of the first node, and a holding unit holding the output signal at a level of a gate-off voltage according to a voltage of the second node in an inactive period of a current stage, in which the holding unit comprises a first diode which applies a clock signal to the second node.
