Abstract: A gate driver includes: a signal generator configured to generate a gate signal, and output the gate signal to a first output terminal; and an inverted signal generator configured to generate an inverted gate signal based on the gate signal, and output the inverted gate signal to a second output terminal, wherein the inverted signal generator includes: a first transistor connected between a first node connected to the second output terminal and a first driving power supply terminal, and including a PMOS transistor; and a second transistor connected between the first node and a second driving power supply terminal, and including an NMOS transistor, and wherein a second node connected to the first output terminal is connected to a gate electrode of each of the first and second transistors.

Abstract: A display device includes a display panel that displays an image and including a first display area, in which a plurality of first pixels is disposed, and a second display area which is adjacent to the first display area and in which a plurality of second pixels is disposed and a gate driving block which overlaps the second display area and transmits driving signals to the plurality of first pixels and the plurality of second pixels. Each of the plurality of first pixels includes a first shielding layer. Each of the plurality of second pixels includes a second shielding layer. A first common voltage is applied to the first shielding layer, and a second common voltage having a voltage level different from a voltage level of the first common voltage is applied to the second shielding layer.
