Abstract:
1. A gate driving circuit comprising: a plurality of stages, each of the plurality of stages configured to output a gate signal, connected to each other one after another, an i-th stage (i is an integer number equal to or greater than 2) among the stages comprising: an output transistor comprising a control electrode connected to a first node, the first node having an electric potential increased by a control signal from a previous stage of the i-th stage, and the output transistor configured to receive a clock signal to output a gate signal of the i-th stage; and a control part comprising at least one control transistor comprising an output electrode connected to the first node, the control part configured to control turn on and off of the output transistor, wherein the at least one control transistor comprises a first control electrode and a second control electrode disposed on a layer different from a layer on which the first control electrode is disposed, and wherein the first control electrode is configured to receive a switching control signal and the second control electrode is configured to receive a reference voltage having a constant positive voltage level.
