Abstract: A display device includes a pixel circuit, a first insulation layer covering the pixel circuit, a first electrode disposed on the first insulation layer, a second electrode disposed on the first insulation layer while being spaced apart from the first electrode, a second insulation layer covering the first electrode, the second electrode, and the first insulation layer disposed between the first electrode and the second electrode, and a light emitting element electrically connected to the first electrode and the second electrode on the second insulation layer and disposed between the first electrode and the second electrode. Here, the second insulation layer includes a first area overlapping the first electrode, a second area overlapping the second electrode, and a stopper area disposed between the first electrode and the second electrode, and the stopper area has a thickness different from that of each of the first area and the second area.
