Abstract

Provided is a display device including a substrate including a display area and a non-display area; a thin-film transistor and a display element on the display area; an organic insulating layer between the thin-film transistor and the display element; a first power supply voltage line arranged to correspond to one side of the display area in the non-display area; a second power supply voltage line spaced apart from the first power supply voltage line; and an inorganic protective layer that covers at least a portion of the second power supply voltage line. The second power supply voltage line includes a first region and a second region. The first region has a stack of a first conductive layer, a second conductive layer, and the organic insulating layer. The second region has a stack of the first conductive layer and the inorganic protective layer.
