Abstract
The present invention provides an organic EL light-emitting apparatus that can compensate a voltage drop caused on a transparent electrode and that can prevent the occurrence of brightness unevenness caused by the voltage drop. A transparent electrode 2, an organic light-emitting functional layer 5, and a back electrode 6 are successively laminated on a light-transmitting substrate 1, and a sealing member 9 for sealing the transparent electrode, the organic light-emitting functional layer, and the back electrode is provided so as to accommodate them between the substrate 1 and the sealing member 9. A conductive layer 10 is formed on the sealing member 9, and conductive columnar members 4 are interspersedly formed between the conductive layer 10 and the transparent electrode 2 in the plane direction of the substrate 1. Accordingly, electric power is supplied to the transparent electrode 2 from the conductive layer 10 through the conductive columnar members 4.
