Abstract
A display apparatus includes a substrate including at least one hole disposed in a hole area of the substrate, a thin film transistor disposed on the substrate, a light-emitting component disposed on the substrate and electrically connected to the thin film transistor, an insulating layer disposed on the substrate, a thin film encapsulation layer disposed on the substrate, and a laser blocking layer. The substrate includes a display area and a non-display area that is disposed between the display area and the hole area. The laser blocking layer is disposed on the insulating layer in the non-display area.
