    Abstract: Provided is a gate driver comprising an inverter inverting a start signal to generate an inverted start signal, a first driver including a first stage generating a bias gate signal to initialize a light emitting element of each of pixels in response to the inverted start signal, and a second driver including a second stage generating a write gate signal to apply data voltages to the pixels in response to the start signal. Accordingly, the gate driver may generate a plurality of gate signals using one start signal. In addition, since the gate driver generates a write gate signal and a bias gate signal using one start signal, a bias operation and a light emitting element initialization operation may be performed in a self-scan period without adding the start signal. Further, a size of the gate driver may be reduced, and accordingly, the gate driver may be efficiently disposed.

    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.
