An image displaying apparatus is capable of maintaining the contrast ratios of displayed images even if the f-value of an optical system of the apparatus is lowered to provide bright images, efficiently utilizing a beam from a light source, minimizing the size and weight of the optical system, and being easy to manufacture. The image displaying apparatus includes first to third reflective polarizing plates ( 120, 121, 122 ) provided for first to third reflective spatial light modulators ( 130, 131, 132 ), respectively. The reflective polarizing plates polarize and separate beams to be injected into the reflective spatial light modulators. In the image displaying apparatus, a color separating optical system has a larger effective diameter than a color composition prism ( 140 ).
