Abstract

An image generation apparatus includes a first reflective optical element that reflects at least part of the light outputted from a light source apparatus and a second reflective optical element disposed in the optical path of the light reflected off the first reflective optical element. A projection optical apparatus has an entrance optical path located in the light exiting optical axis of the image generation apparatus, a deflection member that deflects light having traveled along the entrance optical path, and a passage optical path along which the light deflected by the deflection member travels. The light exiting optical axis of the light source apparatus is parallel to the light incident optical axis of the projection optical apparatus, and the extension of the light exiting optical axis of the light source apparatus intersects with the passage optical path.
