<p>PURPOSE: A light source device, a projecting device, and a projecting method are provided to maintain the formation of a color material and the brightness of a projected picture by a single light source even if luminance is not uniform in every color component. CONSTITUTION: A light source device comprises a first light source(20), a source-light modulator, and a second light source(21). The first light source emits a first source light at a first wavelength band. The source-light modulator comprises a first surface and a second surface. The source-light modulator comprises a first area that outputs a transmissive light from the first surface and a second area that outputs a reflective light from the second surface. The second light source emits a second source light at a second wavelength band, which is different from the first wavelength band. The first source light and the transmissive light are blue light.</p> |
