Abstract:
A gate driving circuit that can be stably driven by improving output characteristics of a last output buffer unit, and a display device comprising the gate driving circuit, are discussed. The gate driving circuit can include a plurality of subordinately connected stages, where an Nth (N being a natural number) stage includes a node controller configured to control voltages of a first node and a second node according to a set signal and a reset signal. The Nth stage can further include a plurality of scan pulse output units configured to receive a plurality of scan clocks, and output each of the scan clocks as a scan pulse according to voltages of the first node and the second node.
