| 20130010370 | OPTICAL PROJECTION SYSTEM AND PROJECTOR INCLUDING THE SAME - An optical modulation device side lens group has different powers in the longitudinal direction and the lateral direction of a liquid crystal panel. Therefore, as the entire system of the optical projection system, the optical modulation device side lens group has different magnification in the longitudinal and lateral directions.
