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.

Abstract: A light-emitting device includes: a plurality of first electrodes respectively in a first sub-pixel, a second sub-pixel, and a third sub-pixel; a second electrode facing the plurality of first electrodes; a first emission layer in the first sub-pixel and configured to emit a first color light; a second emission layer in the second sub-pixel and configured to emit a second color light; a first layer that is integrated with the first sub-pixel, the second sub-pixel, and the third sub-pixel; a first auxiliary layer between the first layer and the first emission layer; and a first intermediate layer between the first auxiliary layer and the first emission layer. The first emission layer includes a first host and a first dopant. The first dopant is configured to emit light having a full width at half maximum (FWHM) of about 35 nm or more.
