摘要:
A light-emitting device includes a light-emitting element having a top surface, a bottom surface opposite to the top surface, and side surfaces connecting the top surface and the bottom surface. An element electrode of the light-emitting element is located on the bottom surface. A phosphor layer is disposed above the top surface of the light-emitting element and having side surfaces. A reflective member covers side surfaces of the light-emitting element and side surfaces of the phosphor layer. A dielectric multilayer film is disposed on at least one of the side surfaces of the light-emitting element and disposed on at least one of the side surfaces of the phosphor layer and not located between the light emitting element and the phosphor layer. The dielectric multilayer film is not provided on an upper surface of the phosphor layer.
