Abstract: A display device includes: a substrate; a display element on the substrate; a capping layer on the display element; and a thin film encapsulation layer on the capping layer, wherein the capping layer includes: a first capping layer on the display element; a second capping layer on the first capping layer, the second capping layer having a refractive index greater than that of the first capping layer; and a third capping layer on the second capping layer, the third capping layer having a refractive index smaller than that of the second capping layer, wherein the second capping layer has a thickness of 30 nanometers (nm) to 60 nm.
