Beschreibung
Zusammenfassung: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.
