Abstract: This invention provides an organic EL light-emitting device, which can prevent the occurrence of brightness unevenness due to resistance of a transparent electrode, in a large surface light-emitting panel of an organic EL element. The organic EL light-emitting device includes an element formation substrate 1, on which an organic EL element 2 including an organic light-emitting layer is stacked, and a sealing substrate 3 for sealing the organic EL element so as to accommodate the organic EL element between the element formation substrate and the sealing substrate. A sealing portion 4 formed of an adhesive is formed in the peripheral edge portion between the element formation substrate 1 and the sealing substrate 3, and a grease layer 5 or a gel layer 5 is accommodated in between the element formation substrate, on which the organic EL element surrounded by the sealing portion is formed, and the plate-shaped sealing substrate so as to adhere to the element formation substrate and the sealing substrate.
