Abstract
An image display system includes an illumination system, a light valve, a polarization beam splitter, and at least one polarizing element. The illumination system includes a light source, a color separator, and a scrolling unit. The light valve processes color beams which are scrolled, according to an input image signal and form a color image. The polarization beam splitter transmits or reflects an incident light beam according to polarization so light from the illumination system advances toward the light valve and light from the light valve advances toward a projection lens unit. A polarizing element may be installed at a path of light traveling toward the polarization beam splitter or a path of light that is reflected by the light valve and travels toward the projection lens unit.
