Abstract: A display device includes a plurality of pixels including a first pixel representing green, where each of the pixels includes a light emitting element including an anode, a light emitting layer, and a cathode. The display device further includes a control layer disposed in a direction in which the light emitting element emits light and overlapping the first pixel, and a transmittance of the control layer at a first wavelength band, within a green wavelength band, is lower than a transmittance at a remaining visible light region such that a decrease in a front luminance spectrum by the control layer is greater than a decrease in a side luminance spectrum by the control 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.
