Abstract:
A display device includes a substrate having first and second pixel areas that respectively emit first and second light, a first electrode that overlaps the first and second pixel areas, a hole transport region that overlaps the first and second pixel areas, a first organic layer disposed on the first electrode to overlap the first pixel area, a second organic layer disposed on the first electrode to overlap the second pixel area, an electron transport region disposed on the first and second organic layers to overlap the first and second pixel areas, and a second electrode disposed on the first and second organic layers to overlap the first and second pixel areas. The first organic layer includes first emission layers that emit first light and a charge generation layer disposed between the first emission layers. At least one of the first emission layers overlaps the first and second pixel areas.
