Patent ID: 8680766

Claim:
An organic EL display device comprising an organic EL element comprising a first electrode, an organic layer including a light emitting layer, and a second electrode, which are sequentially laminated above a first substrate having a circuit formed thereon, the organic EL element being covered with a protective layer including a silicon oxynitride film, wherein the silicon oxynitride film is brought into contact with the second electrode, and wherein the silicon oxynitride film has infrared absorption characteristics including: a Si—O—Si stretching vibration absorption peak appearing at energy lower than 1,000 cm −1 ; an absorption intensity of a Si—N stretching vibration absorption peak appearing in the vicinity of around 870 cm −1 , which is 0.75 or more times the absorption intensity of the Si—O—Si stretching vibration absorption peak; and an absorption peak intensity in a range of 2,000 to 4,000 cm −1 , which is 5% or less of the absorption intensity of the Si—N stretching vibration absorption peak.
