Abstract
A gate driver circuit can include a plurality of stage circuits, in which each of the plurality of stage circuits supplies a gate signal to gate lines arranged in a display panel, and includes an M node, a Qnode, a Qnode, a QB node, a line selector, a Qnode controller, a Qnode stabilizer, an inverter, a QB node stabilizer, a carry signal output circuit portion, and a gate signal output circuit portion, in which a first low-potential voltage level, a third low-potential voltage level, and a fourth low-potential voltage level for operating the gate driver circuit are set to different values, and the gate driver circuit can have a reduced size and better prevent leakage current while also providing more stable gate signals.
