Abstract: A display device may include a pixel disposed in a display area. The pixel may include first and second electrodes; a light emitting element disposed between the first and second electrodes; a first insulating pattern disposed on the light emitting element such that first and second ends of the light emitting element are exposed; a second insulating pattern disposed on the first insulating pattern such that ends of the first insulating pattern are exposed; a third insulating pattern disposed on the second insulating pattern and overlapping ends of the second insulating pattern; a first contact electrode disposed on the first end of the light emitting element, and electrically connecting the first end of the light emitting element to the first electrode; and a second contact electrode disposed on the second end of the light emitting element and electrically connecting the second end to the second electrode.
