Abstract: A display apparatus includes a thin-film transistor located in a display area and including a semiconductor layer and a gate electrode; a storage capacitor located in the display area and including a first capacitor plate, a second capacitor plate, and a dummy capacitor plate overlapping each other; a light-emitting diode electrically connected to the thin-film transistor and the storage capacitor and including a pixel electrode, an interlayer, and a counter electrode; a pad located in a surrounding area adjacent to the display area; a lower electrode pattern layer disposed below the semiconductor layer, at least a portion of the lower electrode pattern layer overlapping the semiconductor layer; and a bridge electrode electrically connecting the semiconductor layer to the lower electrode pattern layer.
