Abstract
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 () provided for first to third reflective spatial light modulators (), 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 ().
