PROBLEM TO BE SOLVED: To provide a light-emitting device that can excite fluorescence substance by a light-emitting element and output light of a light-emission spectrum having all high color rendering indexes.SOLUTION: A light-emitting device includes first and second blue light emitting elements which are different in peak wavelength which is the wavelength of the peak value of a light emission spectrum in a wavelength range of 430-480 nm, and a phosphor layer including a green phosphor which is excited by emission light of the first and second blue light emitting elements and emits green light having a light emission spectrum having a first wavelength having a first intensity and a second wavelength having a second intensity smaller than the first intensity, and a red phosphor which has an absorption spectrum with less absorption at the second wavelength than the first wavelength for green light, and is excited by emission light of the first and second blue light emitting elements to emit red light.SELECTED DRAWING: Figure 1 |
