Abstract:
A light emitting device including a blue light emitting portion configured to emit blue light, a green light emitting portion configured to emit green light, and a red light emitting portion configured to emit red light, in which the blue light emitting portion includes a near-UV light emitting diode chip and a first wavelength conversion portion for wavelength conversion of near-UV light emitted from the near-UV light emitting diode chip, the blue light emitted from the blue light emitting portion includes a first peak wavelength in a wavelength band corresponding to near-UV light and a second peak wavelength in a wavelength band corresponding to blue light, and an intensity of the first peak wavelength is in a range of 0% to 20% of an intensity of the second peak wavelength.
