ABSTRACT:
An image display apparatus includes a polarization conversion element which converts second color light of unpolarized light emitted from a light source into a first linear polarized light, and a light path separation element which separates the second color light emitted from the first and third color light; and performs image display by illuminating a first, a second and a third liquid crystal display elements with the first, second and third color light that pass through the light path separation element, wherein the light path separation element leads a first linear polarized light component of the second color light to the second liquid crystal display element, and wherein the light path separation element leads a second linear polarized light component whose direction of polarization is orthogonal to the first linear polarized light component of the second color light, in a direction different from any of the liquid crystal display elements.
