Abstract: A display device includes a substrate, a partition wall disposed on the substrate and having a plurality of openings, a first emission layer, a second emission layer, and a third emission layer respectively disposed in an opening of the partition wall and emitting light of different colors, a light blocker disposed on the emission layers and including a plurality of openings respectively overlapping the first emission layer, the second emission layer, and the third emission layer, and a color filter disposed in the opening of the light blocker. A separation distance between one edge of the partition wall contacting the second emission layer and the light blocker is greater than a separation distance between the one edge of the partition wall contacting the first emission layer and the light blocker.
