Abstract
A light source device includes: a driving circuit; a blue light emitting element made of a group III nitride semiconductor which has a light outgoing surface on a side opposite to a side with the driving circuit, is arranged on the driving circuit, and is electrically connected to the driving circuit; and a color conversion layer which is in contact with the light outgoing surface and converts a wavelength of light emitted from the light outgoing surface. The light outgoing surface is made of a group III nitride semiconductor.
