A display device includes a data conductive layer including a first power line, a passivation layer with a first opening exposing the first power line, a via layer with a second opening partially overlapping the first opening, a pixel electrode on the via layer, a connection electrode in the first and second openings, a pixel-defining film with an opening overlapping the second opening, a light-emitting layer on the pixel-defining film, the pixel electrode and the connection electrode, and a common electrode connected to the first power line. The data conductive layer includes a data base layer, a data main metal layer, and a data capping layer, the first power line includes a wire connection structure, in which the data main metal layer is recessed from sides of the data capping layer, and the common electrode is connected to the data main metal layer in the wire connection structure.
