Abstract
A gate driver for a display device includes: a clock signal line to transfer a clock signal; and a plurality of stages to sequentially output a gate signal based upon the clock signal in response to a carry signal. The plurality of stages include a plurality of thin film transistors, and at least one of the plurality of thin film transistors includes a thin film transistor including an oxide semiconductor. The at least one thin film transistor includes a first gate electrode and a second gate electrode disposed in different layers, the oxide semiconductor is disposed between the first gate electrode and the second gate electrode, and the first gate electrode and the second gate electrode are connected to receive a common voltage signal.
