Abstract: A gate driver includes first and second stages. Each of the first and second stages includes an output circuit which outputs a scan signal, a carry signal and an inverted carry signal based on voltages of first and second nodes, a first input terminal, a second input terminal, a third input terminal, a first output terminal, and a second output terminal. The first stage further includes a first input circuit which controls the voltages of the first and second nodes thereof based on a start pulse and a signal supplied to the second input terminal. The second stage further includes a second input circuit which controls the voltages of the first and second nodes thereof based on a first carry signal and a first inverted carry signal, and a signal supplied to the second input terminal. The second stage is dependently connected to the first stage.

Abstract: A display device includes gate lines and pixels connected to the gate lines. The display device includes stages which provide gate signals to the gate lines, and first and second gate power lines which transfer a first voltage to the stages. A first stage among the stages includes a first node controller and a first output unit. The first node controller is connected to the second gate power line, and controls a voltage of a first control node. The first output unit is connected to the first gate power line, and outputs a first voltage of the first gate power line as a gate signal in response to a voltage of the first control node.
