Abstract
A display device includes an emissive layer between a plurality of first electrodes and a second electrode, an encapsulation layer on the second electrode, an a touch layer on the encapsulation layer. A plurality of refractive patterns are on the touch layer and overlap the emissive layer, and a refractive film covers refractive patterns. Each of the refractive patterns and the refractive film comprise an organic material, and the refractive index of the refractive film is less than the refractive index of each of the refractive patterns.
