Abstract
A display device includes a substrate, a first set of light emitting structures, a second set of light emitting structures, a diffraction layer, and a refraction pattern. The substrate includes a first region and a second region. The first set of light emitting structures overlaps the first region. The second set of light emitting structures overlaps the second region. The diffraction layer overlaps the first region without overlapping the second region. The refraction pattern overlaps the diffraction layer. The diffraction layer includes first-refractive-index members and second-refractive-index members that are alternately disposed. A refractive index of each of the first-refractive-index members is lower than a refractive index of each of the second-refractive-index members.
