Abstract: A display device includes a base layer, first pixels, second pixels, a power supply line (PSL), a power supply voltage supply circuit (PSVSC), and a feedback wire (FBW). The base layer includes a display area (DA) and a non-display area (NDA) adjacent to the DA. The DA includes a first pixel area (PA) including first pixels and a second PA including second pixels. The second PA protrudes from the first PA. The PSL extends in at least a first direction in the DA. The PSL receives a first power supply voltage (PSV) through a first end of the PSL, and supplies the first PSV to the first and second pixels. The PSVSC supplies the first PSV to the PSL through the first end. The FBW is electrically connected to a second end of the PSL disposed in the second PA. The FBW feeds back the first PSV to the PSVSC.
