Zusammenfassung:A gate driving circuit including a plurality of stages dependently connected to one another. Each stage comprises a gate pad formed at one end of a gate line; a pull-up transistor outputting a gate driving signal for driving the gate line; a capacitor formed with a dielectric substance disposed between a first electrode connected to a gate electrode of the pull-up transistor and a second electrode connected to a drain electrode of the pull-up transistor; a first connecting electrode connecting the gate pad to the second electrode; a holding transistor connected to the pull-up transistor to maintain a voltage level of the gate driving signal; a switching transistor connected to the pull-up transistor and the capacitor to control the holding transistor through the gate driving signal; and a second connecting electrode connecting the second electrode to the gate electrode of the switching transistor.
