Patent ID: 8456084

Claim:
An organic light-emitting device comprising: a substrate including at least a base material; an insulating layer disposed at the substrate; an organic planarizing layer which covers the insulating layer such that the insulating layer is disposed under the organic planarizing layer; at least one organic light-emitting element which (a) includes a pair of electrodes provided on the substrate and an organic compound layer disposed between the pair of electrodes, and (b) provides a light-emitting area; an inorganic sealing layer provided on the organic light-emitting element and the surface of the substrate; and an adhesion layer which is provided between the insulating layer and the inorganic sealing layer in a vertical direction of the substrate and is in contact with the insulating layer and the inorganic sealing layer for improving the adhesiveness of the inorganic sealing layer, wherein the adhesion layer is provided only at the periphery of the light-emitting area in an in-plane direction of the substrate, wherein the adhesion layer is covered with the inorganic sealing layer, so that the adhesion layer is not exposed, and wherein the adhesion layer comprises an inorganic film.
