A display apparatus includes a substrate including a display area and a peripheral area adjacent to the display area, a thin-film transistor located in the display area of the substrate and including a semiconductor layer and a gate electrode overlapping a channel region of the semiconductor layer, a conductive layer disposed between the substrate and the semiconductor layer and including a first electrode located in the display area of the substrate and a pad electrode located in the peripheral area of the substrate, and a first insulating layer disposed between the conductive layer and the semiconductor layer and having a first opening that exposes at least a portion of an upper surface of the pad electrode.
