Abstract: A display device is disclosed that includes a substrate, a thin film transistor, a power line, a pixel electrode, an emission layer, a common electrode, and dummy electrodes. The thin film transistor is disposed on the substrate. The power line is disposed on the substrate and includes a first conductive layer and a second conductive layer having a protrusion part spaced apart from an upper surface of a first conductive layer. The pixel electrode is disposed on the substrate and is electrically connected to a thin film transistor. The emission layer is disposed on the pixel electrode. The common electrode is disposed on the emission layer and contacts the power line. The dummy electrodes are disposed on the same layer as the power line and include the same material as the pixel electrode.
