    Abstract: A display device includes first and second initialization voltage sources and first and second pixel circuits. The first initialization voltage source provides a first initialization voltage. The second initialization voltage source provides a second initialization voltage less than the first initialization voltage. The first pixel circuit includes a first organic light emitting diode. The second pixel circuit includes a second organic light emitting diode with an organic material having a band gap different from a band gap of an organic material in the first organic light emitting diode. The first pixel circuit is coupled to the first initialization voltage source and the second initialization voltage source. The second pixel circuit is coupled to a single initialization voltage source.

    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.
