Zusammenfassung: | A gate driver and a display device using the same are disclosed. The gate driver includes a first transistor configured to pre-charge a Q node, a second transistor configured to raise the output voltage depending on a voltage of the Q node, a third transistor configured to charge a QB node, a fourth transistor configured to lower the output voltage depending on a voltage of the QB node, and a capacitor connected between a gate and a source in at least one of the second transistor and the third transistor. The capacitor has a capacitance greater than a capacitance between the gate and a drain of the transistor to which the capacitor is connected. The capacitor includes an upper capacitor disposed on an organic passivation layer covering the first transistor, the second transistor, the thirdtransistor and the fourth transistor.
