Abstract
In a liquid crystal projection display, first, second and third color components of an input light beam are processed by first, second and third polarizers that are disposed respectively perpendicular to propagation directions of the first, second and third color components. First, second and third liquid crystal modulators modulate the first, second and third color components from the polarizers. First, second and third analyzers process the modulated first, second and third color components, respectively, and are disposed perpendicular to the propagation directions of the first, second and third color components. The first, second and third liquid crystal modulators are disposed respectively at an angle relative to a recombiner unit such that an output light beam can be provided by the recombiner unit to a projection lens group with a propagation direction that is parallel to an optical axis of the projection lens group.
