More Information
Summary:A light-emitting device includes a substrate, first and second light-emitting elements, a first frame, and first and second wavelength conversion members. The first light-emitting element is disposed on a first surface or first wirings of the substrate and electrically connected to the first wirings via first connecting members. The second light-emitting element is disposed on a surface of the first light-emitting element, and electrically connected to the second wirings via second connecting members. The first frame surrounds the first and second light-emitting elements in a top view. The first wavelength conversion member is disposed in a region surrounded by the first frame. The second wavelength conversion member is disposed in at least a part of the region surrounded by the first frame in the top view. A chromaticity of light converted by the first wavelength conversion member differs from a chromaticity of light converted by the second wavelength conversion member.
