Abstract:
An organic electroluminescence display device comprising a plurality of light emitting elements, a sealing film covering the plurality of light emitting elements, and having a top surface which is an inorganic film made of a first inorganic material, a protective film made of an organic material, the protective film covering the sealing film, and a close-fitting layer made of a second inorganic material and located between the top surface of the sealing film and the protective film. The first inorganic material has higher moisture-barrier properties than the second inorganic material, and adhesion between the second inorganic material and the organic material is higher than adhesion between the first inorganic material and the organic material.
