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 a first pixel region and a second pixel region having different widths. First pixels in the first pixel region each include a first transistor. Second pixels in the second pixel region each include a second transistor performing a same function as the first transistor. At least one of a channel width and a channel length of the first transistor of the first and second pixels is be different from one another.
