Abstract: A display device includes a pixel electrode disposed on a substrate, a bank layer covering edges of the pixel electrode and defining light emitting areas and a non-light emitting area, a light emitting layer on the pixel electrode and the bank layer, a common electrode on the light emitting layer, a capping layer on the common electrode, a counter substrate facing the substrate, and an optical member on the counter substrate. The capping layer comprises a first capping layer disposed on the common electrode, and a second capping layer disposed on the first capping layer and overlapping the light emitting areas.
