Abstract: A display apparatus includes a substrate having an opening, a display area around the opening, and a middle area between the opening and the display area, a light-emitting element in the display area, the light-emitting element comprising a pixel electrode, an opposite electrode, and an intermediate layer between the pixel electrode and the opposite electrode, and a disconnection portion in the middle area, the disconnection portion including a first stack structure and a second stack structure on the first stack structure. A 1-1st sub-layer, a 1-2nd sub-layer, and a 1-3rd sub-layer are sequentially stacked in the first stack structure. A 2-1st sub-layer, a 2-2nd sub-layer, and a 2-3rd sub-layer are sequentially stacked in the second stack structure. The intermediate layer and the opposite electrode extend from the display area to the middle area, the intermediate layer and the opposite electrode being disconnected at the disconnection portion.
