摘要： A light emitting device includes a blue light emitting portion emitting blue light; a green light emitting portion emitting green light; and a red light emitting portion emitting red light, wherein the blue light emitting portion includes a near-UV light emitting diode chip and a wavelength conversion portion emitting blue light through wavelength conversion of near-UV light emitted from the near-UV light emitting diode chip, and a peak in a wavelength band corresponding to near-UV light emitted from the blue light emitting portion has an intensity in the range of 0% to 20% of intensity of a peak in a wavelength band corresponding to blue light emitted from the blue light emitting portion. The light emitting device emits white light using the blue light emitting portion, the green light emitting portion, and the red light emitting portion, thereby realizing white light having a similar spectral power distribution to that of sunlight.
