A display apparatus includes a substrate including a display area and a peripheral area outside the display area, a thin film transistor arranged on the substrate corresponding to the display area and including a semiconductor layer and a gate electrode, a pad electrode arranged on the substrate corresponding to the peripheral area and including a material the same as that of the semiconductor layer, and a first insulating layer arranged on the thin film transistor and the pad electrode and including an opening that partially exposes the pad electrode. Accordingly, failure to perform a normal operation by a pixel circuit and a light-emitting element may be prevented.

Display apparatus with exposed pad electrode

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.

Display apparatus and method of manufacturing the same

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.
