Abstract(in English) One problem with front projection displays is that the screen contrast ratio decreases in bright ambient light. We proposed a novel front projection-display system that diffuses only projected light towards the viewing angle range and reflects an ambient light towards the other angle ranges. With this system, we realized a high quality front projection-display with a high contrast ratio even in a bright room.
