Abstract: Embodiments provide a display device that includes first, second, and third light emitting regions, and first, second, and third light emitting elements. The first, second, and third light emitting regions are spaced apart in a plan view. The first, second, and third light emitting elements respectively correspond to the first, second, and third light emitting regions. Each of the first, second, and third light emitting elements includes a first electrode, a second electrode, a first light emitting unit, a second light emitting unit, and a charge generation layer that includes a p-type charge generation layer and an n-type charge generation layer, wherein the p-type charge generation layer includes first, second, and third p-type charge generation layers.

Abstract: A light emitting devices includes a first electrode, a hole transport region on the first electrode, a first emission layer on the hole transport region, the first emission layer to emit light of a first wavelength, a second emission layer on the hole transport region and to emit light of a second wavelength, an electron transport region on the first and second emission layers, and a second electrode on the electron transport region. The first emission layer includes a first sub-emission layer including a first hole transport host and a first sub-dopant to emit the light of the first wavelength, and a second sub-emission layer including a first electron transport and a second sub-dopant to emit the light of the first wavelength. The second emission layer includes a second hole transport host, a second electron transport host, and a second dopant to emit the light of the second wavelength.
