Summary:A solid-sealing type organic EL display device having an excellent mechanical strength, sealed by a highly reliable sealing method and in which the luminescence property is less deteriorated. A laminate film including a thermoplastic adhesive member and a barrier layer against moisture is disposed on an upper electrode that is situated over an organic EL layer. In a sealing part existed in a periphery of the display region, only a metal oxide film which is formed of metal alkoxide exists between an edge of the laminate film and the element substrate. The organic EL element is surrounded only by an inorganic film so that moisture permeation from the outside can be prevented. Moreover the sealing part is composed of the inorganic film having an excellent sealing property against water thereby it is possible to make a width of the sealing part small.
