Abstract: A display apparatus includes a substrate, a pixel layer arranged over the substrate and including a plurality of display elements, an encapsulation member sealing the pixel layer, and a refractive layer arranged on the encapsulation layer and including a first refractive layer and a second refractive layer. The first refractive layer includes openings that correspond to the plurality of display elements, and the second refractive layer includes high refractive particles. The second refractive layer includes a first layer and a second layer, the first layer includes the high refractive particles dispersed in a first concentration, and the second layer includes the high refractive particles dispersed in a second concentration different from the first concentration.
