Abstract
A display apparatus includes a thin film transistor disposed in a display area of a substrate and a display device in the display area that is electrically connected to the thin film transistor, an encapsulation layer that protects the display device, at least one through portion formed in the display area that vertically penetrates the substrate and a plurality of layers stacked on the substrate, and a first groove and a second groove that are spaced apart from each other and that surround the at least one through portion. A flow-restriction portion is disposed in a region between the first groove and the second groove that protrudes upwards from the substrate and confines an organic encapsulation layer of the encapsulation layer.
