Abstract

A gate driver includes first to nstages. A kstage among the first to nstages includes a first transistor including a second terminal electrically connected to a first control node, a fifth transistor including a gate electrically connected to an inverting control node, a sixth transistor including a gate electrically connected to a second control node, a fourth transistor including a gate which receives a low gate voltage, a first terminal electrically connected to a first control node, a second terminal electrically connected to a second control node, and a back gate, and a seventh transistor including a gate which receives a voltage of the inverting control node of a k+1stage, a first terminal which receives a voltage of the first control node or the second control node of a k−1stage, and a second terminal electrically connected to the back gate of the fourth transistor.
