An active matrix organic light-emitting display device comprises a substrate, an active layer having a channel region and source and drain regions positioned on a predetermined region of the substrate. A first electrode is connected to one of the source and drain regions and extended onto the substrate, and has a multi-layer structure formed of at least one conductive layer. A second electrode is spaced from the first electrode to be connected to the other of the source and drain regions, and has the same stacked structure formed of conductive layer as the first electrode. An organic functional layer having at least an organic emission layer is positioned on the first electrode. A third electrode is positioned on the organic functional layer.
