Abstract: A display device includes a base substrate including first, second, and third light-emitting areas respectively emitting light of different colors and a non-light-emitting area surrounding the first, second, and third light-emitting areas, an organic layer, and a conductive pattern disposed in the non-light-emitting area on the base substrate and constituting a blocking capacitor together with the charge generation layer. The organic layer includes a hole transport region disposed on the base substrate, a lower light-emitting layer disposed in each of the first, second, and third light-emitting areas on the hole transport region, a charge generation layer disposed on the lower light-emitting layer, an upper light-emitting layer disposed in each of the first, second, and third light-emitting areas on the charge generation layer, and an electron transport region disposed on the upper light-emitting layer.
