Abstract: A display apparatus includes a substrate with a display area and a peripheral area surrounding the display area, a thin-film transistor disposed on the display area of the substrate, a pad unit disposed on the peripheral area of the substrate, a first insulating layer disposed on the display area of the substrate and exposing the pad unit, the first insulating layer including a first portion disposed on the thin-film transistor, a second portion, and a third portion between the first portion and the second portion, and a light-emitting device disposed on the first portion of the first insulating layer and electrically connected to the thin-film transistor. A top surface of the first insulating layer includes a first top surface of the first portion, a second top surface of the second portion, and a connecting surface of the third portion. The first top surface of the first portion is higher than the second top surface of the second portion. The connecting surface connects the first top surface and the second top surface with each other and is sloped.
