Abstract:
A light-emitting device includes a substrate, a frame body, a light-emitting element, a wavelength converter, and a light reflecting portion. The light-emitting element includes a semiconductor light-emitting layer on a support substrate. The wavelength converter is disposed on an upper surface of the light-emitting element. The light reflecting portion covers side surfaces of the light-emitting element and the wavelength converter and is formed of a translucent resin containing light reflective particulate fillers. The light reflecting portion includes a first region extending along an upper surface of the light reflecting portion, a second region that is disposed under the first region and has a content rate of the particulate fillers lower than a content rate of the first region, and a third region that is disposed under the second region and has a content rate of the particulate fillers lower than the content rate of the second region.
