A display apparatus is provided. The display apparatus can include a substrate hole penetrating a device substrate, light-emitting devices spaced away from the substrate hole, and at least one separating device between the substrate hole and the light-emitting devices. Each of the light-emitting devices can include a light-emitting layer between a first electrode and a second electrode. The separating device can surround the substrate hole. The separating device can include at least one under-cut structure. The under-cut structure can include a depth and a length, which are larger than a thickness of the light-emitting layer. Thus, in the display apparatus, the damage of the light-emitting devices due to external moisture permeating through the substrate hole can be prevented.
