Abstract
A spectroscopic 3D image display device according to the present disclosure includes: at least one first projection type image display device that uses first illumination light to display an image; at least one second projection type image display device that uses second illumination light to display an image; and a system controller that carries out control so that the first and second projection type image display devices are synchronously driven. A light source device of the first projection type image display device emits, with prescribed output power, first blue light having the central wavelength λa, and switches the intensity of the output power and emits third blue light. A light source device of the second projection type image display device emits, with prescribed output power, second blue light having the central wavelength λb. The central wavelengths λa, λb, and λc satisfy λb≤λc<λa.
