Abstract: A shift register of the present disclosure includes a plurality of stages. Each stage includes transistors belonging to a first group for activating a Q node, transistors belonging to a second group for discharging odd and even QB nodes, transistors belonging to a third group for being activated by the odd and even QB nodes and for discharging the Q node, and a sensing circuit for sensing a threshold voltage of at least one of the transistor belonging to the third group at a period when the Q node is discharged. The shift register of the present disclosure avoids the problem of erroneous operation due to lowering of device characteristics.
