Abstract: A display device comprises a substrate, a sub-pixel disposed on the substrate and that includes a pixel electrode, a light emitting layer, and a common electrode, a pixel defining layer that defines the sub-pixel, a capping layer disposed on the pixel defining layer, a micro lens disposed on the capping layer and that overlaps the sub-pixel; and a total reflection pattern disposed on the capping layer and that overlaps the pixel defining layer and surrounds the micro lens. The micro lens has a refractive index greater than a refractive index of the total reflection pattern and less than or equal to a refractive index of the capping layer.
