Abstract
A light emitting device may include: a substrate including a plurality of unit light emitting regions; and first to fourth insulating layers sequentially on the substrate. Each of the unit light emitting regions may include: at least one light emitting element on the first insulating layer, the at least one light emitting element having a first end portion and a second end portion in a length direction thereof; first and second partition walls on the substrate, and the first and second partition walls being spaced apart from each other; a first reflective electrode on the first partition wall and a second reflective electrode on the second partition wall; a first contact electrode on the first reflective electrode, the first contact electrode connecting the first reflective electrode and the first end portion of the light emitting element; a second contact electrode on the second reflective electrode, the second contact electrode connecting the second reflective electrode and the second end portion of the light emitting element; and a conductive pattern provided between the first insulating layer and the first contact electrode, the conductive pattern surrounding the first and seco…
