PROBLEM TO BE SOLVED: To provide a multi-wavelength light source device reducing coherency between a plurality of laser beams while keeping the wide color gamut as a feature of laser sources. SOLUTION: A multi-wavelength light source device includes three light source devices 11 to 13. Each of the light source device includes a plurality of light emitting elements 23a to 23e, and a dispersing section 22 making wavelengths of light beams emitted from the respective light emitting elements 23a to 23e different from each other, a spectral line width of the emitted light beam in each of the light source devices 11 to 13 is equal to or greater than 0.2 nm, a wavelength of the emitted light beam in the light source device 11 is greater than 612 nm, a wavelength of the emitted light beam in the light source device 12 is greater than 525 nm and smaller than 538 nm, and a wavelength of the emitted light beam in the light source device 13 is greater than 465 nm and smaller than 468 nm.
