Patent ID: 7414360

Claim:
An organic electroluminescent devices, comprising: a transparent substrate; a plurality of transparent electrodes on the transparent substrate and arranged to extend on the transparent substrate in a first direction along the transparent substrate; a plurality of connecting electrodes on the transparent substrate, arranged to extend on the transparent substrate in a direction orthogonal to the first direction of the plurality of transparent electrodes, and arranged to avoid contact with the plurality of transparent electrodes; a plurality of scan-connecting electrodes formed on the plurality of connecting electrodes; an insulation layer on a predetermined area of the transparent substrate, an edge portion of the plurality of transparent electrodes, a portion of the plurality of connecting electrodes, and an edge portion of the plurality of scan-connecting electrodes, the insulation layer formed not to be in contact or cover emission parts of the plurality of transparent electrodes and contact parts of the plurality of scan-connecting electrodes, wherein an area (A E ) of one of the emission parts of the plurality of transparent electrodes, number (N) of the emission parts of the plurality of transparent electrodes formed on a scan line, and an area (A C ) of one of the contact parts of the plurality of scan-connecting electrodes are determined under the formula of [(A E ×N)/100≦A C ]; an organic layer formed on the emission parts of the plurality of transparent electrodes; and a scan electrode layer formed on the contact parts of the plurality of scan-connecting electrodes and arranged to cover emission parts of the plurality of transparent electrodes, and at least a portion of the insulation layer.
