1. A display apparatus comprising:
a substrate comprising a first area, a second area, and a third area between the first area and the second area, the first area having a through hole;
a display element at the second area, the display element comprising a pixel electrode, an opposite electrode, and an intermediate layer between the pixel electrode and the opposite electrode, and the intermediate layer comprising at least one organic material layer;
a thin-film encapsulation layer covering the display element, and comprising a first inorganic encapsulation layer, a second inorganic encapsulation layer, and an organic encapsulation layer between the first inorganic encapsulation layer and the second inorganic encapsulation layer;
a first dam portion at the third area, the first dam portion being adjacent to the second area;
a second dam portion at the third area, and spaced from the first dam portion; and
at least one groove at the third area,
wherein the at least one organic material layer of the intermediate layer is disconnected by the at least one groove,
wherein a groove from among the at least one groove is between the first dam portion and the second dam portion, and at least a part of the organic encapsulation layer is at the at least one groove, and
wherein the display apparatus further comprises a metal layer between the substrate and the opposite electrode, the metal layer defining a portion of the at least one groove.
