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.
