Abstract: A display device includes: a display panel in which a plurality of pixels are arranged; a plurality of gate lines disposed in the display panel and transmitting a gate signal to the plurality of pixels; a gate driver disposed in the display panel and including a plurality of stages for generating the gate signal and outputting the gate signal to the plurality of gate lines; and a plurality of clock signal lines disposed in the display panel and transmitting a clock signal to the plurality of stages. Each stage of the plurality of stages includes a clock signal terminal connected to one of the plurality of clock signal lines to receive the clock signal, a first output terminal connected to a corresponding gate line to output the gate signal, and a first transistor and a second transistor connected to the first output terminal. The stages have a substantially same area, and a size of the second transistor of a first stage disposed at an upper portion of the display panel is different from a size of the second transistor of a second stage disposed at a lower portion of the display panel.
