ORGANIC LIGHT-EMITTING DIODE (OLED) DISPLAY AND METHOD OF MANUFACTURING THE SAME

An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a substrate, a plurality of sub-pixels over the substrate, wherein each of the plurality of sub-pixels includes an OLED layer comprising an OLED, wherein the OLED comprises a first electrode, a second electrode facing the first electrode, and an emitting layer therebetween, an encapsulation layer over the OLED layer and comprising at least one inorganic layer and at least one organic layer, a refractive layer comprising a first refractive index layer that is located over the encapsulation layer and has a recess and a second refractive index layer that is located over the first refractive index layer, wherein the second refractive index is greater than the first refractive index, and wherein an upper surface of the refractive layer is flat.
