Abstract:
Disclosed are a gate driving circuit including a first gate output buffer circuit and a control circuit, and a display device including the same. The control circuit may include a first transistor connected between a first driving voltage node and a QB node, two second transistors connected in series between the QB node and a second low level voltage node, a third transistor connected between a connection node of the two second transistors and the first driving voltage node, a fourth transistor connected between the gate node of the first transistor and the first driving voltage node, and two fifth transistors connected in series between the gate node of the first transistor and the second low level voltage node. A connection node of the two fifth transistors may be electrically connected to the source node or the drain node of the third transistor.
