Abstract
A display apparatus includes a substrate including a display area and a peripheral area; a thin-film transistor disposed on the substrate and including a semiconductor layer; a conductive layer disposed between the substrate and the semiconductor layer and including a pad electrode disposed in the peripheral area; a first insulating layer disposed between the conductive layer and the semiconductor layer and including a first opening exposing at least a part of an upper surface of the pad electrode; and a second insulating layer disposed on the thin-film transistor and including a second opening coinciding with the first opening, wherein an opening area of the second opening of the second insulating layer is greater than an opening area of the first opening of the first insulating layer.
