Abstract:
1. A light source device comprising: a light source; a light source side reflective plate to which the light source is fixed; an emission side reflective plate facing the light source side reflective plate; and fixing means for fixing the light source side reflective plate and the emission side reflective plate, the light source being constituted by one or a plurality of light-emitting diodes, the emission side reflective plate being formed so that a portion thereof facing the light source has the highest optical reflectance and the lowest optical transmittance while the optical reflectance decreases and the optical transmittance increases as being farther away from the light source, and the distance between the light source side reflective plate and the emission side reflective plate being greatest at a portion where the light source is disposed and decreases as being farther away from the portion where the light source is disposed.
