Abstract
An organic EL device includes a lower electrode formed on a substrate; an organic EL layer formed on the lower electrode; an upper electrode formed on the organic EL layer; a sealing member for sealing the lower electrode, organic EL layer and upper electrode on the substrate. The sealing member is made of an aluminum material coated with an insulating layer in its inner surface. Since the inner surface of the sealing member is coated with the insulating layer, contact of the sealing member with the upper electrode produces no trouble. Since the surface of the insulating layer is porous, by removing the gas from the surface of the insulating layer , impurities in the internal space can be taken into a large number of pores of the insulating layer . In such a configuration, a thin-profile and reliable organic EL device can be provided which can be manufactured with improved efficiency of manufacture and at reduced production cost.
