Abstract: The present invention relates to a light emitting device and a manufacturing method thereof. One aspect of the present invention relates to the light emitting device which includes a light emitting chip and a wavelength conversion unit which is arranged on the optical path of the light emitting chip and includes a first wavelength conversion material to increase conversion efficiency according as a wavelength is increased in a part of band in the wavelength range of light emitted from the light emitting chip and a second wavelength conversion material to decrease the conversion efficiency. According to one embodiment of the present invention, obtained is the light emitting device with a color dispersion reducing structure when a plurality of light emitting devices are manufactured.
