Abstract

A display apparatus is disclosed that includes a substrate, a display element, a transistor, and a pad. The substrate includes a display area and a peripheral area. The display element is disposed on the display area. The transistor is electrically connected to the display element. The pad is disposed on the peripheral area and having a multilayered structure. The pad includes a pad metal layer, a first pad protective layer disposed on the pad metal layer, and a second pad protective layer interposed between the pad metal layer and the first pad protective layer. The second pad protective layer includes a different material from the first pad protective layer. The transistor includes a semiconductor layer disposed on the substrate, a gate electrode disposed on a gate insulating layer that covers the semiconductor layer, and a connection electrode arranged on an interlayer insulating layer covering the gate electrode. The connection electrode has the same multilayered structure as the multilayered structure of the pad, and the connection electrode is connected to the semiconductor layer.
