We have developed a lens‐shiftable front projector of DLP™ system adopting a nontelecentric system that uses no prisms. The f‐number of projection lens was composed smaller than the f‐number of illumination optical system, and that, a fixed aperture was provided on the incidence side of the projection lens. This arrangement allowed us to realize a bright and high‐contrast optical system with a compact structure.
