A light emitting device may include: a substrate including emission areas; a first electrode disposed on the substrate, and a second electrode spaced apart from the first electrode; at least one light emitting element disposed on the substrate, and including a first end and a second end; an insulating layer disposed on the light emitting element and allowing the first and second ends of the light emitting element to be exposed; a first contact electrode electrically connecting the first electrode with the first end of the light emitting element; a second contact electrode electrically connecting the second electrode with the second end of the light emitting element; and a passivation pattern disposed on each of the first and second contact electrodes. The first and second contact electrodes may be disposed on the insulating layer and spaced apart from each other and may be electrically separated from each other.
