Abstract
A display apparatus includes a substrate defining an opening area and including 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, 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 and second inorganic encapsulation layer; and a partition wall on the organic insulating layer and including 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.
