Abstract: A display device includes a substrate, a first insulating layer, a power lines, and connection lines. The substrate includes a peripheral area adjacent to at least one side of a pixels area. The first insulating layer including one or more contact holes. The power line is in the peripheral area and provides a driving voltage to pixels. The power line includes a first metal layer on the substrate and a second metal layer connected to the first metal layer through the contact hole. The connection lines extend to the peripheral area from the pixels and overlap part of the power line. The power line includes a first area in which the first and second metal layers are electrically connected through the contact hole. The connection line does not overlap the first area of the power line.
