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.
