Abstract:
A white light emitting device includes: a blue light emitting diode (LED) which emits blue light; and a resin packing unit which encapsulates the blue LED, wherein the resin packing unit includes a first wavelength conversion material which, in response to being excited by the blue light, emits green light, a second wavelength conversion material which, in response to being excited by the blue light, emits red light, and a complex compound which absorbs light of a region in which the green light and the red light are mixed, the light of the region being included in white light implemented through a mixture of the green light and the red light excited together with the blue light.
