ABSTRACT:
A light source device includes a shade that is capable of reflecting light from both of its front and back surfaces and is wider than a hot-cathode tube. The shade is disposed between the hot-cathode tube and the optical member so as to maintain a certain distance from the optical member. Light radiated from the hot-cathode tube to the optical member side is reflected by the shade, and thereby prevented from directly illuminating the optical member. Further, the shade functions as a pseudo light source wider than the hot-cathode tube due to the reflectivity of the optical member side surface of the shade, and thereby formation of lamp images can be suppressed.
