Abstract
The present disclosure relates to a gate driving circuit and a display device using the circuit. A gate driving circuit according to an aspect of the present disclosure comprises a Q node controller, a QB node controller, and an output unit generating a pulse-type output signal by controlling charging and discharging of an output terminal according to the voltages of the Q node and the QB node, and the QB node controller controls the voltage of the QB node in an alternating manner during a non-scan period in which the Q node controller outputs a low level voltage for the Q node.
