摘要:
A light-emitting device is provided, which includes a substrate, a light-emitting element configured to emit light having a first wavelength, the light-emitting element having a pair of electrodes and being formed above the substrate, a metal layer interposed between the substrate and the light-emitting element and having a planar configuration, and a wavelength converting layer formed on the metal layer. The periphery of the metal layer is at least partially constituted by a plurality of projected portions and a plurality of recessed portions. The plurality of projected portions locates outside of the light-emitting element. The wavelength converting layer absorbs at least part of the light emitted from the light-emitting element and converts the first wavelength, thereby light having a second wavelength differing in wavelength from the first wavelength is emitted.
