A light source device includes a first light source for emitting first light, a first wavelength conversion element for converting the first light into second light, a first optical layer for transmitting the first light and reflecting the second light, a second light source for emitting third light, and a light guide section for guiding the second light and the third light. The first wavelength conversion element has a first surface on which the first light is incident via the first optical layer, and a second surface and a third surface which intersect the first surface and face away from each other. The second light source is disposed in a region on the second surface side of the light guide section. The first optical layer reflects the third light in addition to the second light, and a portion of the second light and the third light travels through the light guide section and is emitted from the region on the third surface side of the light guide section.
