Abstract: A display device includes a pixel array disposed in a display area, a connection pad disposed in a pad area, and a transfer wiring electrically connected to the connection pad to transfer a signal to the pixel array. The pixel array includes a light-emitting element including a first electrode including a multi-layered structure including a metal layer and a metal oxide layer, an organic light-emitting layer disposed on the first electrode, and a second electrode disposed on the organic light-emitting layer. The connection pad includes an upper pad conductive layer having a single-layered structure including a metal oxide.
