Abstract: A display device may include a substrate. A first light emitting element is disposed on the substrate. A second light emitting element is disposed on the substrate and is positioned adjacent to the first light emitting element. A first encapsulation layer is disposed on the first light emitting element and the second light emitting element. A light path control layer is disposed on the first encapsulation layer. The light path control layer includes a first pattern overlapping the first light emitting element and having a first refractive index and a second pattern overlapping the second light emitting element and having a second refractive index that is greater than the first refractive index.
