A light-source unit is disposed such that illumination light is horizontally emitted relative to an oblong screen. Three liquid-crystal display panels respectively have a liquid-crystal display surface of a rectangle. The display panels are disposed in a lengthwise posture and in a state that longer sides of the display surfaces are parallel with each other. At the same time, all the longer sides are perpendicular to a reference plane. A projection optical system is provided with a reflex mirror for perpendicularly bending an optical path. A rotation optical system for rotating projection light by 90 degrees is constituted of the reflex mirror and a plane mirror disposed behind the screen.
