    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 substrate having a pixel area with at least a first rounded corner portion and first to third non-pixel areas arranged sequentially along an outer circumference of the pixel area. An internal circuit in the first non-pixel area has a first end portion adjacent to the first rounded corner portion of the pixel area. The first end portion of the internal circuit is rounded in accordance with the first rounded corner portion. A plurality of routing wires are in the third non-pixel area below the pixel area. The routing wires extending to the pixel area via the second non-pixel area and the first non-pixel area. The routing wires include at least a first routing wire connected to the pixel area passing an area of the first end portion of the internal circuit.
