Abstract: According to an embodiment of the disclosure, an electronic device comprises a substrate including an active area including a light emitting area and a non-light emitting area and a non-active area around the active area, a first electrode disposed on the substrate, an organic layer disposed on the first electrode, a second electrode including a first layer disposed on the organic layer and a second layer disposed on the first layer, and an encapsulation layer disposed on the second electrode. In the active area, the first layer of the second electrode may include at least one first hole to expose a top portion of the organic layer. Thus, there may be provided an electronic device free from an increase, over time, in the number of dark spots due to foreign bodies or even with fewer dark spots.
