Organic electroluminescence display device

An organic electroluminescence display device comprising:

• 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,
• wherein the encapsulating member includes at least one organic layer and at least one inorganic layer which are alternately disposed therein, wherein
• an inorganic layer from among the at least one inorganic layer disposed most adjacent to the display member 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, and
• each of the remaining inorganic layers among the at least one inorganic layer except for the inorganic layer disposed most adjacent to the display member and the at least one organic layer has a single layer structure, wherein the inorganic layer disposed most adjacent to the display member comprises:
• a first sub inorganic layer disposed on the display member;
• and
• a second sub inorganic layer disposed on the first sub inorganic layer,
• wherein each of the first sub inorganic layer, and the second sub inorganic layer includes one of the first layers and one of the second layers.
