Abstract
A head-mounted image display apparatus is provided with: an image display element; a projection optical system that projects an image displayed by the image display element, so as to be enlarged; a reflective screen onto which the image is projected by the projection optical system; and a combiner disposed between the projection optical system and the screen. The combiner transmits the image light from the projection optical system and directs it to the screen, and reflects the image light reflected at the screen and directs it to the user's pupil.
