A display device includes a substrate in which first and second pixel areas respectively emitting first and second light respectively having different emission wavelengths from each other are defined, a first electrode on the substrate to overlap the first and second pixel areas, a hole transport region on the first electrode to overlap the first and second pixel areas, first and second organic layers on the hole transport region to respectively overlap the first and second pixel areas, an electron transport region on the first and second organic layers to overlap the first and second pixel areas, and a second electrode on the electron transport region to overlap the first and second pixel areas. The first organic layer includes first emission layers emitting the first light and a first charge generation layer between the first emission layers, and the second organic layer includes a single second emission layer emitting the second light.
