    Abstract: An organic light-emitting diode display includes an organic light-emitting display device including a first electrode, an intermediate layer including an organic emission layer, and a second electrode; a first inorganic encapsulation layer on the second electrode; a second inorganic encapsulation layer on the first inorganic encapsulation layer; and an organic encapsulation layer on the second inorganic encapsulation layer. A refractive index of the first inorganic encapsulation layer is higher than a refractive index of the second inorganic encapsulation layer. The first inorganic encapsulation layer has an extinction coefficient of 0.02 to 0.07 and a refractive index of 2.1 to 2.3 at a blue wavelength.

    Abstract: A display device includes a substrate, a display unit on the substrate, and an encapsulating unit configured to seal the display unit from external moisture or oxygen and including an organic layer and an inorganic layer. The inorganic layer includes a first layer, a second layer on the first layer, and one or more first particles between the first and second layers. A method of manufacturing a display device includes forming a display unit on a substrate and sealing the display unit from external moisture or oxygen by forming an encapsulating unit. The forming of the encapsulating unit includes forming an inorganic layer. The forming of the inorganic layer includes forming a first layer, forming one or more first particles on an upper surface of the first layer, and forming a second layer on the first layer and the first particles.

    Abstract: An electronic device includes a base substrate including a hole region including a recessed region and a display, a circuit device layer including insulating layers, each of which has an opening overlapped with the recessed region, a display element layer including an organic light emitting element including a charge control layer, which is between first and second electrodes and is overlapped with the display and hole regions, an encapsulation layer including first and second inorganic encapsulation layers and an organic encapsulation layer therebetween, and a protection inorganic layer between the insulating layers and first inorganic encapsulation layer. The charge control layer may include a first pattern on one of the insulating layers overlapped with the hole region and a second pattern spaced apart from the first pattern and in the recessed region. The protection inorganic layer may cover the first pattern and the second pattern.
