Abstract
A display device for improving an outcoupling efficiency of emitted light is disclosed. The display device includes a substrate, a subpixel arranged on the substrate, the subpixel including an organic light emitting diode having an emission portion that emits light, a first passivation layer disposed on the organic light emitting diode, at least one lens positioned on the first passivation layer, the at least one lens disposed in a position corresponding to the emission portion of the organic light emitting diode, a cover layer covering the at least one lens, and a second passivation layer disposed on the cover layer. A refractive index of the at least one lens is greater than a refractive index of the cover layer.
