Abstract: Disclosed is an organic EL display device including: a base substrate (10); an organic EL element (18) provided over the base substrate (10); and a sealing film (25a) covering the organic EL element (18). The sealing film (25a) includes a plurality of buffer layers (19a, 21a, 23a) each comprised of an inorganic film, and a buffer layer (20a, 22a) comprised of an organic film and provided between adjacent two of the plurality of buffer layers (19a, 21a, 23a). The buffer layer (20a, 22a) includes, in its peripheral edge portion surrounding the organic EL element, a flat thin portion (20t, 22t) which is thinner than the rest of the buffer layer (20a, 22a) above the organic EL element (18).

Abstract: An EL display device in which the adhesion between a substrate and a sealing film is increased and in which the occurrence of cracks in the sealing film is reduced is provided. A lower inorganic film (31) has a multilayer structure including a first inorganic layer (34), which is in contact with the substrate and an EL element, and a second inorganic layer (35). The absolute value of the film stress of the first inorganic layer (34) is less than the absolute value of the film stress of the second inorganic layer (35), and the film thickness of the first inorganic layer (34) is less than the film thickness of the second inorganic layer (35).

Abstract: The present invention includes a frame-shaped sealing material, a filling layer, and a support. The frame-shaped sealing material is provided between a TFT substrate and a counter substrate, and is configured to seal an organic EL element (electroluminescent element) along with the TFT substrate and the counter substrate. The filling layer is composed of a liquid filler, and is filled in the space between the counter substrate, a sealing film, and the sealing material. The support is located inside the sealing material and between the TFT substrate and the counter substrate, and also supports the TFT substrate and the counter substrate.
