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.

2. An image display apparatus that displays an image by projecting a light modulated according to an image signal on a surface to be irradiated, the image display apparatus comprising:
-
a housing; and a projection optical system that is housed in the housing, and projects the light modulated according to the image signal from an optical engine unit, the 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, wherein the projection lens and the second mirror are arranged in such a manner that an optical axis of the projection lens substantially matches an optical axis of the second mirror, and shift the light from the optical engine unit to a specific side from the optical axis of the projection lens, the surface to be irradiated is on the outside of the housing, and a light traveling from the projection lens to the first mirror travels in a direction along the surface to be irradiated. - View Dependent Claims (3, 4, 5, 6, 7, 8)
