A light emitting device includes: a die-mounting base having a mounting surface; a light emitting diode mounted on the mounting surface of the die-mounting base and having a top surface facing in a normal direction normal to the mounting surface of the die-mounting base; a first wavelength-converting layer of a first wavelength-converting material formed on the mounting surface of the die-mounting base, enclosing the light emitting diode, and having a top surface; and a second wavelength-converting layer of a second wavelength-converting material formed on the top surface of the first wavelength-converting layer and having a top surface that is aligned with the top surface of the light emitting diode in the normal direction, and that has an area smaller than the top surface of the first wavelength-converting layer and not smaller than the top surface of the light emitting diode.
