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.

Abstract: A flexible display device includes a substrate including a non-bending area and a bending area adjacent to the non-bending area, and a crack prevention pattern disposed in the bending area. The bending area includes a first area having a first stress when bending, a second area having a second stress less than the first stress when bending, and a third area having a third stress less than the second stress when bending. The crack prevention pattern includes a plurality of crack prevention lines. The number of the crack prevention lines in the first area is greater than the number of the crack prevention lines in the third area.
