Abstract: An organic light-emitting diode (OLED) display and a method of manufacturing an OLED display are disclosed. In one aspect, the display includes a substrate and a thin-film transistor including an active layer, a gate electrode, a source electrode, and a drain electrode formed over the substrate. A gate insulating layer is formed between the active layer and the gate electrode, and an interlayer insulating layer is formed between the gate electrode and the source and drain electrodes. Also, a planarization layer is formed over the source and drain electrodes, and a pixel electrode is formed over the planarization layer. The display also includes capacitor including a first electrode formed on the same layer as the active layer and a second electrode formed of the same material as the pixel electrode. A pixel-defining layer covers opposing ends of the pixel electrode; an emission layer formed over the pixel electrode.

Abstract: A display device may include at least one optical control unit including first refractive index layers, second refractive index layers, and an optical compensation layer. The second refractive index layers may be stacked in an alternating manner with the first refractive index layers and may have a refractive index different from that of the first refractive index layers. The optical compensation layer may be disposed at least on the uppermost refractive index layer of the first and second refractive index layers to be in contact with the uppermost refractive index layer or below the lowermost refractive index layer of the first and second refractive index layers to be in contact with the lowermost refractive index layer. The optical compensation layer may have a thickness less than those of the first and second refractive index layers.
