An illuminating apparatus includes a condensing optical system for converting light from a light source into convergent light, and a first convex lens array for receiving the convergent light, and a collimating optical system for making a plurality of light beams from the first convex lens array parallel to one another. In addition, a polarization converting element array individually converts the plurality of light beams from the collimating optical system into polarized lights.
