Abstract: A stage includes an output, an input, signal processors, and a stabilizer. The output supplies a voltage of a first or second power source to an output terminal based on voltages of first and second nodes. The input controls voltages of third and fourth nodes based on signals to a first and second input terminals. A first signal processor controls the voltage of the first node based on the voltage of the second node. A second signal processor is connected to a fifth node and controls the voltage of the first node based on a signal to a third input terminal. A third signal processor controls the voltage of the fourth node based on the voltage of the third node and the signal to the third input terminal. The stabilizer is connected between the second signal processor and input to control voltage drop widths of the third and fourth nodes.

Abstract: A display device includes first pixels in a first pixel region and connected to first scan lines and second pixels in a second pixel region connected to second scan lines. The second pixel has a width less than the first pixel region. The display device also includes a first scan driver to supply first scan signals to the first scan lines, a second scan driver to supply second scan signals to the second scan lines, a first signal line to supply a first driving signal to the first scan driver and the second scan driver, and a signal delay circuit connected to the first signal line to delay the first driving signal.
