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 including a first end portion and a second end portion in a length direction thereof; first and second banks on the substrate; a first electrode on the first bank and a second electrode on the second bank; a first contact electrode on the first electrode; a second contact electrode on the second electrode; and a conductive pattern provided between the first insulating layer and the first contact electrode, the conductive pattern surrounding the first and second electrodes when viewed on a plane.
