Abstract: A display device includes a plurality of scan lines and a plurality of data lines; and a plurality of pixels connected with the scan lines and the data lines, wherein at least one pixel of the plurality of pixels includes a pixel circuit having at least one transistor, an insulating layer covering the pixel circuit, a first electrode disposed on the insulating layer and electrically connected to the pixel circuit, a second electrode disposed on the insulating layer and spaced apart from the first electrode, and a light-emitting element electrically connected to the first electrode and the second electrode. The first electrode includes a first region having at least one first resistance and a plurality of second regions having a second resistance higher than the first resistance, the second electrode includes a third region having at least one third resistance and a plurality of fourth regions having a fourth resistance higher than the third resistance, and the light-emitting element is electrically connected to the first electrode at one of the first regions and the second electrode at one of the third regions.
