Zusammenfassung:A light-emitting device includes: a light-emitting element emitting a first light having a first peak wavelength; a first wavelength conversion member contacting a side surface of the light-emitting element and including a wavelength conversion material absorbing at least a portion of the first light and emitting a second light having a second peak wavelength different from the first peak wavelength; a second wavelength conversion member on the first wavelength conversion member, the second wavelength conversion member including a wavelength conversion material absorbing at least a portion of the first light and emitting a third light having a third peak wavelength different from the first and second peak wavelengths; and a first light-reflective member on the second wavelength conversion member and at least on the light-emitting element. A continuous light-emitting surface includes a side surface of the first wavelength conversion member and a side surface of the second wavelength conversion member.
