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.
