Patent ID: 8921846

Claim:
An organic EL device comprising a power feeding part and an organic-EL-element forming part, wherein the organic-EL-element forming part includes a plurality of unit EL elements formed on a substrate, and wherein the organic-EL-element forming part is constituted by a plurality of series-connected parts each formed by a plurality of the unit EL elements that are electrically connected in series in a forward direction, the series-connected parts being electrically connected to the power feeding part in parallel, each of the plurality of series-connected parts including a corresponding reverse polarity series-connected part that is connected to the power feeding part so as to have reverse polarity as compared to the other of the series-connected parts, wherein end portions of the series-connected parts, which are electrically divided in a unit EL element row, are electrically connected to each other by a layer of organic EL elements, wherein the unit EL element row is electrically divided by a plurality of the serially connected unit EL elements receiving electric power through the central portion and through both end portions, wherein the central portion is a series-connected part that is not an end portion, and wherein each series-connected part receives power from the layer of organic EL elements.
