The light-emitting device of the embodiment includes a light-emitting element that emits blue excitation light, and a yellow phosphor that is formed on the light-emitting element and is excited by the excitation light to emit yellow light, and is excited by the excitation light to emit green color. At least one of a fluorescent green phosphor or a red fluorescent red phosphor excited by excitation light, and having a peak wavelength of 520 nm or more and less than 660 nm, and a peak wavelength of the excitation light In the case of shifting, the wavelength at which the peak wavelength of the fluorescent light is also shifted in the same direction is shifted from the phosphor. |
