Claim:
1. A projector comprising: a light source; image forming units that adjust an intensity of light emitted from said light source on a per-pixel basis and form image light; a projection lens that projects image light that is formed in said image forming units to an outside; a first optical system that guides light of a first wavelength that is emitted from said light source to said projection lens; and a second optical system that guides light of a second wavelength that is emitted from said light source to said projection lens; wherein an f-number of said first optical system is greater than an f-number of said second optical system, wherein: said image forming units include: a first image formation element that forms image light of said first wavelength that is irradiated on said projection lens and a second image formation element that forms image light of said second wavelength that is irradiated on said projection lens; said first optical system and said second optical system guide light of said first wavelength to said first image formation element, guide light of said second wavelength to said second image formation element, and have a common separating/synthesizing optical system that synthesizes light of said first wavelength and light of said second wavelength that are reflected by said first and second image formation elements; and said first optical system includes a convex lens between said separating/synthesizing optical system and said first image formation element.
