Abstract:
A display device may include a first electrode, a pixel defining layer disposed on the first electrode, the pixel defining layer having a pixel opening that exposes the first electrode, an emission layer disposed in the pixel opening and on the first electrode, a second electrode disposed on the emission layer, a first refractive layer disposed on the second electrode and being an organic refractive layer, a second refractive layer disposed on the first refractive layer and being an organic refractive layer, the second refractive layer having a first opening that overlaps the pixel opening, and a third refractive layer disposed on the second refractive layer, the third refractive layer having a second refractive index greater than a first refractive index of the second refractive layer.
