<P>PROBLEM TO BE SOLVED: To provide a projector capable of making a reflector of a light source thin, making in-plane illumination distribution of an optical modulation device uniform as compared with a case of one light, and suppressing color unevenness in a surface of a screen projection picture and luminance unevenness. <P>SOLUTION: In a projector, each of a first light source device 110 and a second light source device 120 includes a light-emitting tube 20, a reflector 30 for reflecting light emitted from the light-emitting tube 20, and a secondary mirror 40 disposed on the opposite side to the reflector of the light-emitting tube 20 and reflecting the light emitted from the light-emitting tube 20 toward the reflector 30. The reflector 30 and the secondary mirror 40 have shapes made from a part of a concave mirror. The reflector 30 of the first light source device 110 and the reflector 30 of the second light source device 120 are disposed in a state of being rotated by 180 degrees when viewed from light-emitting sides each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
