ABSTRACT:
An organic electroluminescent device including a transparent substrate; transparent electrodes extended in one direction on the substrate; connecting electrodes for current supply formed in a crossing direction of the transparent electrodes, not to overlap the transparent electrodes, on one side of the substrate; scan-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.
