<p><P>PROBLEM TO BE SOLVED: To provide a projector capable of preventing the contrast of a projected image from being degraded and, at the same time, capable of reducing color unevenness. <P>SOLUTION: The projector 1 comprises: a light source device 411; a color separating optical system 42; liquid crystal panels 441, 441R, 441G, and 441B; a cross dichroic prism 444; and a projection lens 46, wherein an optical filter 500 for reflecting a prescribed spectral component in a luminous flux is disposed between a dichroic mirror 421 and a dichroic mirror 422 where an angle by which the luminous flux expands falls within 20°with respect to an illumination optical axis L of the luminous flux in the middle of an optical path from the light source device 411 to a luminous flux-emitting surface of the projection lens 46. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
