1. A display apparatus comprising:
a substrate defining an opening area and comprising a display area and an intermediate area between the opening area and the display area;
an inorganic insulating layer in the display area and the intermediate area;
a pixel circuit in the display area;
an organic insulating layer on the pixel circuit;
a pixel electrode on the organic insulating layer and electrically connected to the pixel circuit, an intermediate layer on the pixel electrode, and an opposite electrode on the intermediate layer;
a thin-film encapsulation layer on the opposite electrode 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; and
a partition wall on the organic insulating layer in the intermediate area and comprising at least two dams,
wherein the inorganic insulating layer is in contact with the thin-film encapsulation layer in an area between the partition wall and the opening area; and
wherein each of the intermediate layer and the opposite electrode extends to the intermediate area and covers the partition wall.
