Abstract
A gate driving circuit includes a first type of stage circuit for outputting a first gate signal and a second type of stage circuit for outputting a second gate signal, and further including a bias transistor for supplying, when turned-on, a bias voltage to a shield metal positioned to overlap with a semiconductor layer of a specific transistor among a plurality of transistors included in the first type of stage circuit, thereby preventing a leakage current from occurring inside the gate driving circuit.
