Abstract
Disclosed is a shift register capable of stably generating an output even when the threadhold voltage of a pull-down switching element is raised due to degradation of the pull-down switching element. The shift register includes a plurality of stages each comprising a node controller comprising an inverter to control a voltage at a reset node in accordance with a voltage at a set node, and an output unit to output a scan pulse based on at least one of the voltage at the set node and the voltage at the reset node. The shift register further includes an inverter voltage controller for controlling a high-level inverter voltage supplied to each inverter of the stages based on the voltage at at least one reset node in at least one of the stages.
