Abstract: A display device includes a substrate. A light emitting element layer is disposed on the substrate. The light emitting element layer includes a plurality of emission areas. Each of the emission areas comprises a light emitting element emitting light. A thin film encapsulation layer is on the light emitting element layer. The thin film encapsulation layer comprises a first inorganic encapsulation film, a first organic encapsulation film on the first inorganic encapsulation film, and a second inorganic encapsulation film on the first organic encapsulation film. A light control layer includes a first light blocking layer disposed on the thin film encapsulation layer and having a first opening, and a first light transmitting layer disposed on the first light blocking layer. The first light transmitting layer includes an organic layer. A refractive index of the first light transmitting layer is greater than a refractive index of the first organic encapsulation film.
