A projector including a lighting device for emitting light including first, second and third colored light beams. A first dichroic mirror separates the light into the first colored light beam by reflecting the light in a certain wavelength range and transmitting the light in another wavelength range and transmitting the light in another wavelength range. A second dichroic mirror separates the other colored light beams into the second and third colored light beams by reflecting the light in a certain wavelength range and transmitting the light in another wavelength range. The second dichroic mirror separates the light from the lighting device into the colored light beams. The projector including a first color combining optical system for combining the colored light beams to emit a first image light beam.
