A mass-production packaging means suitable for mass-production packaging of an organic luminescent display. An organic electroluminescent display panel on which an organic luminescent device has been formed is first provided. Then, an UV laser is used to clean the surface of the organic electroluminescent display panel. A molding compound is applied on the organic electroluminescent display panel by a sizing system. Subsequently, a lid is aligned with the organic electroluminescent display panel and lamination is performed. Finally, the molding compound is irradiated with UV light to be cured. The package is thus completed.
