1. A light source device comprising:
a substrate having a supporting surface;
a light source disposed at a supporting surface side and configured to emit first light in a first wavelength range;
a first optical member having a first optical layer facing the supporting surface and reflecting the first light emitted from the light source;
a first wavelength conversion layer disposed on the supporting surface and having a light incident surface which the first light enters, the first wavelength conversion layer being configured to convert the first light into second light in a second wavelength range different from the first wavelength range;
a second wavelength conversion layer disposed at a first wavelength conversion layer side with respect to the first optical layer and configured to convert the first light into third light in a third wavelength range different from the first wavelength range; and
a light emitting portion formed by at least the substrate and the first optical member, wherein
the first optical layer is inclined with respect to the light incident surface and further reflects the second light and the third light,
the second wavelength conversion layer converts a part of the first light emitted from the light source into the third light,
the first wavelength conversion layer converts a part of the first light emitted from the second wavelength conversion layer into the second light, and
the light emitting portion emits the first light, the second light, and the third light.
