Abstract
A display apparatus includes: a substrate including a display area in which thin film transistors and display devices electrically connected to the thin film transistors are arranged and a first non-display area outside the display area; a through portion vertically penetrating the substrate; a second non-display area between the through portion and the display area; and an encapsulation layer on the display devices and including a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer, which are sequentially stacked. The first inorganic encapsulation layer and the second inorganic encapsulation layer extend to the through portion and directly contact each other in the second non-display area, and the first inorganic encapsulation layer directly contacts another inorganic layer thereunder in the second non-display area.
