Provided is an organic electroluminescence display device including a base member, a display member disposed on the base member and including an organic electroluminescent element; and an encapsulating member disposed on the display member and encapsulating the display member. The encapsulating member includes a first inorganic layer disposed on the display member; a first organic layer disposed on the first inorganic layer; and a second inorganic layer disposed on the first organic layer. The first inorganic layer has a multilayer structure in which first layers having a first refractive index and second layers having a second refractive index different from the first refractive index are alternately disposed. Each of the first organic layer and the second inorganic layer has a single layer structure.
