GATE DRIVING CIRCUIT AND A DISPLAY DEVICE INCLUDING THE GATE DRIVING CIRCUIT

A gate driving circuit includes driving stages. Each of the driving stages applies each of gate signals to each of gate lines of a display panel. A k-th (k is a natural number equal to or greater than 2) driving stage includes a first output transistor, a capacitor, and first and second control tran...

Zusammenfassung:A gate driving circuit includes driving stages. Each of the driving stages applies each of gate signals to each of gate lines of a display panel. A k-th (k is a natural number equal to or greater than 2) driving stage includes a first output transistor, a capacitor, and first and second control transistor. The first output transistor includes a control electrode connected to a first node, an input electrode receiving a clock signal, and an output electrode outputting a k-th gate signal. The capacitor is connected between the output electrode of the first output transistor and the control electrode of the first output transistor. The first control transistor applies a first control signal to a second node to control a voltage of the first node before the k-th gate signal is output. The second control transistor is diode-connected between the second node and the first node.
