Abstract
A light-emitting device in which a light-emitting element and a substrate are reliably bonded to each other and which has high operation stability is provided. The light-emitting device includes the substrate, the light-emitting element disposed on the substrate with a bonding layer interposed therebetween, and a resin body configured to surround and cover entire side surfaces of the light-emitting element, and have a bottom surface having any of a curved surface shape and a planar surface shape that faces the substrate and is configured to be distant from the substrate between the resin body and the substrate as a distance from the side surface of the light-emitting element increases.
Claims21
A light-emitting device comprising:
- a substrate;
- a light-emitting element disposed on the substrate with a bonding layer interposed therebetween;
- a resin body configured to surround and cover entire side surfaces of the light-emitting element, and have a bottom surface having any of a curved surface shape and a planar surface shape that faces the substrate and is configured so that the distance between the resin body and the substrate increases as a distance from the side surface of the light-emitting element increases;
- and
- a reflective film disposed on an outer peripheral side surface of the resin body.
A light-emitting device comprising:
- a substrate;
- a light-emitting element disposed on the substrate with a bonding layer interposed therebetween;
- and
- a resin body configured to surround and cover entire side surfaces of the light-emitting element, and have a bottom surface having any of a curved surface shape and a planar surface shape that faces the substrate and is configured so that the distance between the resin body and the substrate increases as a distance from the side surface of the light-emitting element increases, wherein
- the resin body is formed of a resin material having a reflectivity with respect to light emitted from the light-emitting element.
