A white light emitting device may include a blue light emitting diode configured to emit blue light and a plurality of wavelength conversion materials configured to convert the blue light into light having different wavelengths based on being excited by the blue light, and emit white light based on the converting, wherein the emitted white light is associated with an Illuminating Engineering Society (IES) TM-30-15 Fidelity Index (R f ) in a range of 78 to 89, an IES TM-30-15 Chroma Change by Hue Index R cs15 in a range of 7% to 16%, and an IES TM-30-15 Chroma Change by Hue Index R cs16 in a range of 7% to 16%, and a color difference between a reflection spectrum of a white specimen of the emitted white light, and International Commission on Illumination (CIE) Standard illuminant D65, that is equal to or less than 106. |
