ABSTRACT:
A projection optical system including a projection lens, a first mirror that reflects a light from the projection lens, and a second mirror that widens an angle of a light from the first mirror by reflecting the light projects a light modulated according to an image signal from an optical engine unit. A third mirror reflects a light from the projection optical system. A screen transmits a light from the third mirror. An optical axis of the projection lens substantially matches an optical axis of the second mirror, and the light from the optical engine unit is shifted to a specific side from the optical axis of the projection lens.
