Abstract
An organic EL element section () is formed on a circuit formation section () formed on a circuit board (). The organic EL element section () is covered with a protective layer () including an SiNOfilm. The SiNOfilm has infrared absorption characteristics including: an Si—O—Si stretching vibration absorption peak appearing at energy lower than 1,000 cm; an absorption intensity of an Si—N stretching vibration absorption peak appearing in the vicinity of around 870 cmwhich is 0.75 or more times an 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, which is 5% or less of the absorption intensity of the Si—N stretching vibration absorption peak. Thus, the protective film having an excellent moisture-blocking property may be obtained, and life property of an organic EL display device may be improved.
