Abstract: A display apparatus includes a substrate including a display area including a first pixel area and a second pixel area which are adjacent to each other along a first direction, and a peripheral area outside the display area, a organic insulating layer disposed over the substrate, a connection metal layer disposed on the organic insulating layer, and a planarization layer covering the connection metal layer. The planarization layer includes a first inner surface defining a contact hole corresponding to the first pixel area and exposing at least a part of a connection metal layer to outside the planarization layer, the first inner surface being a forward-tapered inclined surface, and a second inner surface defining a 1-1st hole which is between the first pixel area and the second pixel area along the first direction and exposes a part of the organic insulating layer to outside the planarization layer, the second inner surface being a reverse-tapered inclined surface.
