Abstract

A light-emitting device includes: a plurality of first electrodes respectively disposed in a first subpixel, a second subpixel, and a third subpixel; a second electrode facing the plurality of first electrodes; a first emission layer disposed in the first subpixel to emit a first-color light; a second emission layer disposed in the second subpixel to emit a second-color light; a first layer disposed between the second electrode and each of the first emission layer and the second emission layer, and integrated with the first subpixel, the second subpixel, and the third subpixel; a hole transport region disposed between the plurality of first electrodes and each of the first layer, the first emission layer, and the second emission layer; a first auxiliary layer disposed between the hole transport region and the first emission layer; and a first intermediate layer disposed between the first auxiliary layer and the first emission layer.
