ABSTRACT:
A head-mounted image display apparatus having an exit pupil that is enlarged without causing an increase in the size of a relay optical system or a reduction in the size of a projected image. The head-mounted image display apparatus has an image display device (1) having a display surface for displaying an image, a relay optical system (2) for transmitting the image displayed on the display surface of the image display device (1) to form an image of the display surface, and an ocular optical system (4) for projecting the image transmitted by the relay optical system inside an observer's eyeball as an enlarged image. A numerical aperture (NA) enlarging element is disposed at a position conjugated with the display surface with respect to the relay optical system (2). Thus, pupil alignment is facilitated without causing an increase in the size of the relay optical system (2) or a reduction in the size of the projected image. Also, provided as a technique whereby field curvature of the ocular optical system is corrected to provide a flat image for observation.
