Abstract: A display device includes a first pixel area including a first pixel electrode and a first organic light emitting layer, a tandem pixel area including a tandem pixel electrode, a first tandem organic light emitting layer and a second tandem organic light emitting layer, a capping layer including a first capping layer corresponding to the first organic light emitting layer and a tandem capping layer corresponding to both the first tandem organic light emitting layer and the second tandem organic light emitting layer, and a common electrode between the first capping layer and the first organic light emitting layer and between the tandem capping layer and the second tandem organic light emitting layer. Each of the first capping layer and the tandem capping layer has a thickness, and the thickness of the tandem capping layer is smaller than the thickness of the first capping layer.

Abstract: A display device includes a display module and a window module. The display module includes a base layer, a light emitting element layer that is on the base layer and includes a light emitting element, an encapsulation layer on the light emitting element layer, and a color filter layer on the encapsulation layer. The light emitting element includes a first electrode, a second electrode that is on the first electrode and includes transparent conductive metal oxide, and a light emitting layer between the first electrode and the second electrode, and a distance between the first electrode and the second electrode is a primary resonance distance for light emitted from the light emitting layer. The encapsulation layer includes a single first inorganic layer directly on the light emitting element layer, an organic layer on the first inorganic layer, and a second inorganic layer on the organic layer.
