Abstract
A light-emitting device is provided. The light-emitting device includes a substrate and a base on or defined by the substrate. A light-emitting element is above the base. An adhesive fixes the light-emitting element above the base. A sealant seals the light-emitting element and includes a phosphor that emits fluorescent light when stimulated by light from the light-emitting element. In a plan view of the base and the light-emitting element, a span of at least part of the base is less than or equal to a corresponding span of the light-emitting element.
