Abstract: A display apparatus includes a display element including a first emission layer disposed on a substrate and a second emission layer disposed on the first emission layer, a first capping layer disposed on the display element, a second capping layer disposed on the first capping layer, a thin-film encapsulation layer including a lower inorganic encapsulation layer in contact with the second capping layer, and a light-blocking layer disposed on the thin-film encapsulation layer and including an opening corresponding to an emission area of the display element. The lower inorganic encapsulation layer has a refractive index greater than a refractive index of the second capping layer.
