Claim:
1. A color separating and/or combining system configured to guide a first color light in a light beam from a light source to a first light modulation element and to guide a second color light that is different in wavelength from the first color light to a second light modulation element, the color separating and/or combining system comprising: a first polarization element configured to guide one of the first color light and the second color light in a direction different from a direction of the other color light based on polarization directions of the first color light and the second light; a first phase difference imparting portion; and a first optical portion configured to guide the first color light to the first light modulation element and to suppress the second color light from being guided to the first light modulation element, wherein the first phase difference imparting portion and the first optical portion are provided between the first light modulation element and the first polarization element, and wherein the first optical portion is provided between the first polarization element and the first phase difference imparting portion.
