ABSTRACT:
In an organic EL display device, an organic EL multilayer structure is disposed in a gastight space defined between a substrate and a shield member and filled with an inert gas. The organic EL multilayer structure includes organic materials having a Tg of at most 140.degree. C. The shield member is a continuous member free of a filling port. The shield member is joined to the substrate with a UV-curing epoxy resin adhesive of the cationic curing type. The inert gas in the space has a water content of at most 100 ppm. The steps of forming layers on substrates to form organic EL multilayer structures and the steps of adhesively joining shield members to the substrates are carried out in inert gas atmospheres.
