Abstract
A light emitting device includes a substrate, a light emitting element, a plurality of bumps and a cover member. The bumps are disposed between the substrate and the light emitting element to mount the light emitting element on the substrate. The bumps include a plurality of first bumps bonded to a first electrode of the light emitting element, and a plurality of second bumps bonded to a second electrode of the light emitting element. The first bumps are spaced apart from exposed portions of a first semiconductor layer of the light emitting element. The first bumps include a plurality of large bumps and a plurality of small bumps each having a smaller surface area than each of the large bumps in a plan view. The cover member covers the light emitting element, the bumps, and the substrate.
