According to one embodiment, a light-emitting device includes a substrate, a light reflection layer, a plurality of light-emitting elements, and a sealing member. The substrate includes an insulating layer constituted of epoxy resin using an acid anhydride as a hardening agent or one of a polyimide resin, a polyethylene terephthalate resin, and a fluororesin. The light reflection layer is formed on the insulating layer. The light reflection layer includes a metallic light-reflecting surface higher in optical reflectance than the insulating layer. The light-emitting elements are mounted on the light-reflecting surface. The sealing member is constituted of a material having gas permeability and translucency, and is formed on the insulating layer to seal the light reflection layer and the light-emitting elements. |
