A projector includes an illumination device, a color separation system, a light combining system, a projection system, and an optical adjustment portion. The color separation system separates the light emitted from the illumination device into blue light, red light, and green light. The light combining system can have a first dichroic filter reflecting one of blue light or red light, and a second dichroic filter reflecting green light which are placed in a crossed state and can combine image lights of respective colors exiting from the first through third light modulation devices. The projection system can project a combined light exiting from the light combining system while correcting chromatic aberrations of magnification of blue light and red light with respect to green light. The optical adjustment portion can adjust a size of an image light corresponding to the green light of the combined light exiting from the light combining system.
