Abstract

A display device includes a substrate, a light emitting diode disposed on the substrate and that emits light that has a preset color, a capping layer disposed on the light emitting diode and that has a thickness of about 540 angstroms to about 640 angstroms, and a thin film encapsulation layer disposed on the capping layer. As the capping layer has a predetermined thickness, a reflectance of external light is reduced, a color bleeding phenomenon is reduced, and the luminous efficiency of the light emitting diode is increased.
