More Information
Summary: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.
