Abstract: In an organic EL display device (electroluminescent device) equipped with an organic EL element (electroluminescent element), the organic EL element is encapsulated by a TFT substrate (substrate), a counter substrate, and a sealing resin. A desiccant layer and a highly-moisture-permeable layer are laminated in this order on the organic EL element. The highly-moisture-permeable layer is in direct contact with the sealing resin.

Abstract: An organic EL display device 1 includes: an organic EL element 4 provided above an element substrate 10; and a sealing film 2 formed above the element substrate 10 so as to cover the organic EL element 4, and made of silicon nitride (SiNx). The sealing film 2 is comprised of a first sealing layer 25, a second sealing layer 26 provided on the surface of the first sealing layer 25, and a third sealing layer 27 provided on the surface of the second sealing layer 26. This organic EL display device 1 is characterized in that a ratio of an SiN-group content to an NH-group content is higher in the first and third sealing layers 25 and 27 than in the second sealing layer 26 based on the absorption area ratio determined by FT-IR measurement.
