An organic light emitting display device may include a plurality of pixels in pixel regions defined on a substrate, each of the pixels being coupled to a current scan line, a data line, a first power source, a second power source and a third power source, wherein each of the pixels includes a pixel circuit having a plurality of transistors and one or more capacitors, and an organic light emitting diode (OLED) including a first electrode and coupled to the pixel circuit, the OLED configured to emit light with a luminance corresponding to a driving current flowing from the first power source to the second power source via the pixel circuit, wherein the third power source is configured to supply a constant voltage to the pixel circuit through a supply line, and wherein the supply line is in a same layer and of a same material as the first electrode.
