Abstract
An organic electroluminescence display device includes a first electrode, a second electrode on the first electrode, and a light-emitting unit between the first electrode and the second electrode, the light-emitting unit including a first sub-light-emitting unit on the first electrode and including a first emission layer, a first charge generation layer on the first sub-light-emitting unit, a second sub-light-emitting unit on the first charge generation layer and including a second emission layer, a second charge generation layer on the second sub-light-emitting unit, and a third sub-light-emitting unit on the second charge generation layer and including a third emission layer, wherein each of the first emission layer and the second emission layer includes a first host, the third emission layer includes a second host different from the first host, and a thickness of the second emission layer is 1.0 nm or less.
