An opposing substrate which is subjected to desiccant application, baking, UV cleaning, UV sealant application, or the like and an element substrate having EL elements formed thereon are affixed together by applying a sealing liquid such as silicon oil in a vacuum. Subsequently, when exposed to a normal atmosphere, the opposing substrate and the element substrate are adsorbed to each other while a predetermined gap is maintained in between. In this state, the UV sealant is cured with UV irradiation. It is thus possible to enclose the sealing liquid between the opposing substrate and the element substrate using a simple manufacturing method.
