Abstract: The present invention relates to the organic electroluminescent device forming a contact part contacting with a scan electrode layer on a scan-connecting electrode, and supplying electric current to an emission part through the contact part. The organic electroluminescent device according to one embodiment of the present invention includes a transparent substrate; a plurality of transparent electrodes for the anode, extended in one direction on the substrate; a plurality of connecting electrodes for current supply formed in the crossing direction to the extended direction of the transparent electrodes, not to overlap the transparent electrodes, on one side of the substrate; a plurality of scan-connecting electrodes formed on the connecting electrodes; an insulation layer formed to cover a predetermined area of the substrate, the transparent electrodes, the connecting electrodes, and the scan-connecting electrodes except the emission parts of the transparent electrodes and the contact parts of the scan-connecting electrodes, wherein the area (AE) of the emission part, the number (N) of the emission parts formed on a scan line, and the area (AC) of the contact part are determined under the formula of [(AE×N)/100≦AC]; an organic layer formed on the emission parts of the transparent electrodes; and a scan electrode layer formed to cover the contact parts, the emission parts, and the insulation layer.
