Abstract: A display apparatus includes a substrate, a thin-film transistor, a display element, a pad, a contact layer, and a pad-protecting layer. The substrate includes a display area and a peripheral area outside the display area. Each of the thin-film transistor and the display element is arranged in the display area. The pad is arranged in the peripheral area. The contact layer is electrically connected to the pad. The pad-protecting layer is on the contact layer and exposes a portion of the contact layer to the outside. The pad includes a first pad layer and a second pad layer. The first pad layer is connected to a connection wiring through a first contact hole. The second pad layer is spaced apart from the first pad layer and is connected to the first pad layer through a second contact hole.
