简介 PROBLEM TO BE SOLVED : To provide a semiconductor light emitting device which has compatibility between color reproducibility and light emission efficiency at high level, and to provide an image display using the same. SOLUTION : The semiconductor light emitting device includes a semiconductor light emitting element, a green phosphor emitting green light and a red phosphor emitting red light. The green phosphor is a rare earth activated inorganic phosphor, and the red phosphor is a semiconductor particle phosphor. The minimum among respective differences between respective wavelengths at local minima of an absorption spectrum of the red phosphor and the peak wavelength of an emission spectrum of the green phosphor is not more than 25 nm.
