Abstract
An image display system includes a projector, a transparent screen, and a polarization adjuster. The projector projects image light. The transparent screen diffuses the image light that has been projected, to display an image. The polarization adjuster adjusts the image light that is to enter the transparent screen so that the image light is p-polarized.
