Organic electroluminescence display device

Abstract

An organic electroluminescence display device includes a first electrode, a first light emitter on the first electrode, the first light emitter including a first light emitting layer, a first charge generation layer disposed on the first light emitter, a second light emitter on the first charge generation layer, the second light emitter including a second light emitting layer, and a second electrode on the second light emitter. The first light emitter includes a first electron injection enhancing layer on the first light emitting layer. The second light emitter includes an electron injection suppressing layer on the second light emitting layer, the electron injection suppressing layer having electron mobility less than that of the first electron injection enhancing layer.
