A display apparatus includes: a cover panel; a display panel on the cover panel; and a cover window on the display panel. The display panel includes: a substrate having a first surface facing the cover panel, and a second surface opposite to the first surface, the substrate including: a display area including a plurality of pixels; a first peripheral area outside the display area, and overlapping with the cover panel; and a second peripheral area outside the first peripheral area; a display layer on the second surface of the substrate, and including a pixel circuit; and a thin-film encapsulation layer on the display layer. The first surface of the substrate includes: a 1-1 surface parallel to the second surface; and a 1-2 surface inclined from the 1-1 surface and located at least in the second peripheral area.
