    Abstract: A display device may include a pixel electrode, a pixel defining layer on the pixel electrode and having a pixel opening that exposes at least a portion of the pixel electrode, an emission layer on the pixel electrode in the pixel opening, an opposite electrode on the emission layer, a first refractive layer on the opposite electrode and having a refractive opening, the first refractive layer having a first refractive index, and a second refractive layer on the first refractive layer and having a second refractive index greater than the first refractive index. A maximum inclination angle of a sidewall of the first refractive layer exposed by the refractive opening with respect to a lower surface of the first refractive layer may be between about 65 degrees and about 90 degrees.
