Abstract: A light emitting device includes light emitting elements having light extraction faces, respectively. A light transmissive member includes a lower face facing the light extraction faces, an upper face opposite to the lower face in a height direction, and first to fourth side faces that are connected to the lower face and the upper face. An area of the lower face is larger than a sum of areas of the light extraction faces. An area of the upper face is smaller than the area of the lower face. The second side face is substantially parallel to the first side face. The third side face and the fourth side face are provided between the first side face and the second side face and opposite to each other. The third side face and the fourth side face approach as approaching from the lower face to the upper face in the height direction.

Abstract: A light-emitting device includes a light-emitting element, first and second light-transmissive members disposed on the light-emitting element, a light-guiding member, and a light-reflective member. A perimeter of a lower surface of the first light-transmissive member is disposed inwardly of a perimeter of an upper surface of the light-emitting element in a plan view. The light-guiding member is in contact with a portion of lateral surfaces of the second light-transmissive member and covers the upper surface of the light-emitting element and the lower surface and lateral surfaces of the first light-transmissive member. The light-guiding member contains a resin material, and has convex lateral surfaces. The light-reflective member covers the lateral surfaces of the light-guiding member and at least the portion of the lateral surfaces of the second light-transmissive member exposed from the light-guiding member. The light-reflective member does not cover the upper surface of the second light-transmissive member.

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.
