Abstract
A rear-projection-type display apparatus projects an image formed by a display element with a light beam emitted from a light source on a screen that is larger than the display element through a projection lens. The rear-projection-type display apparatus includes a reflective optical-element group having at least two reflecting mirrors provided between the projection lens and the screen to deflect a light from the projection lens.
