  • Publication number: 20240136476
    Abstract: A light-emitting device includes a support including a wall portion; a light-emitting element placed on the support and surrounded by the wall portion in a plan view; a first light-transmissive member having a first outer surface and a second outer surface, which is located above the first outer surface and is located inside the first outer surface in the plan view, and covering the light-emitting element and the wall portion; and a light-shielding member covering the first light-transmissive member. The first outer surface and the second outer surface are exposed from the light-shielding member, and a surface roughness of the first outer surface is rougher than a surface roughness of the second outer surface.

  • Patent number: 10749082
    Abstract: A method of manufacturing a light emitting device includes: providing a substrate and a plurality of light sources disposed on the substrate; and forming a plurality of sealing members, each covering a respective one of the plurality of light sources, by supplying a sealing material onto the substrate through a plurality of nozzles of a discharge device. The step of forming the plurality of sealing members includes: performing a first forming step, in which at least one of the sealing members is formed such that a portion of the sealing material is retained dangling from a respective at least one of the plurality of nozzles as at least one dangling thread portion, and successively performing a second forming step, which is started while the at least one dangling thread portion of the sealing material is retained dangling from the at least one of the plurality of nozzles of the discharge device.
