Abstract
A light source device includes: a light guide plate having first and second internal reflection planes facing each other; a first light source applying first illumination light from a side surface of the light guide plate into an interior thereof; a second light source facing the second internal reflection plane, and applying second illumination light to the second internal reflection plane; and a reflective member between the second internal reflection plane and the second light source. The second internal reflection plane is provided with a total-reflection region allowing the first illumination light to be reflected in a total-internal-reflection manner whereas allowing the second illumination light to pass therethrough, and a scattering region allowing the first illumination light to be reflected and scattered. The reflective member is disposed in a position corresponding to the scattering region, and reflects light having passed through the scattering region, toward the first internal reflection plane.
