Abstract
A light source device includes a wavelength conversion element including a substrate and a wavelength conversion layer that is retained by the substrate. The wavelength conversion layer absorbs a portion of incident first color light to output second color light in a wavelength range different from the first color light while outputting an unabsorbed portion of the first color light, in which a portion of the substrate and the wavelength conversion layer has a function of diffusing the first color light.
