Summary:To provide an organic EL display device capable of being manufactured with a good yield even when a particle-like solid desiccant is dispersed in a filler.SOLUTION: An organic EL display device comprises: a first substrate including a first principal surface; a frame-like sealing layer provided on the first principal surface; a second substrate integrated with the first substrate via the sealing layer and including a second principal surface facing the first principal surface; a display part provided on a principal surface 2a and in a sealing space; and a filler filled in the sealing space and dispersed with a particle-like solid desiccant. The display part comprises an organic EL element including the first electrode, organic EL layer, and second electrode laminated in this order from the second principal surface side; an organic sacrificial layer provided on and in contact with the second electrode, and a first inorganic protection layer provided on and in contact with the organic sacrificial layer. The filler overlapping the organic EL element in a thickness direction of the first substrate is located between the first inorganic protection layer and the first substrate.SELECTED DRAWING: Figure 2 【課題】充填材に粒子状の固体乾燥剤が分散される場合であっても、歩留まりよく製造可能な有機ＥＬ表示装置を提供する。【解決手段】有機ＥＬ表示装置は、第１主面を有する第１基板と、第１主面上に設けられる枠状の封止層と、封止層を介して第１基板と一体化されており、第１主面に対向する第２主面を有する第２基板と、第２主面上であって、封止空間内に設けられる表示部と、封止空間内に充填されると共に粒子状の固体乾燥剤が分散される充填材と、を備える。表示部は、第２主面側から順に積層された第１電極、有機ＥＬ層、及び第２電極を有する有機ＥＬ素子と、第２電極上に接して設けられる有機犠牲層と、有機犠牲層上に接して設けられる第１無機保護層と、を備える。第１基板の厚さ方向において有機ＥＬ素子に重なる充填材は、第１無機保護層と第１基板との間に位置している。【選択図】図２
