Abstract:
Provided is a gate driving circuit comprising an N-th stage and an N+1-th stage. The N-th stage outputs an N-th scan gate signal based on an N-th scan clock signal, a voltage of a QN node, and a voltage of a QBN node and to output an N-th carry signal based on an N-th carry clock signal, the voltage of the QN node, and the voltage of the QBN node. The N+1-th stage outputs an N+1-th scan gate signal based on an N+1-th scan clock signal, a voltage of a QN+1 node, and the voltage of the QBN node and an N+1-th carry signal based on an N+1-th carry clock signal, the voltage of the QN+1 node, and the voltage of the QBN node. The N-th stage and the N+1-th stage share an inverting circuit. The inverting circuit controls the QBN node based on a third signal. N is a positive integer.
