ABSTRACT:
A head- or face-mounted image display apparatus having compact and wide-field ocular optical systems designed to form readily fusible virtual images. When ocular optical systems having curvature of field are used for observer's right and left eyes, right and left virtual images (13R and 13L) are curved. The right and left ocular optical systems (11R and 11L) having curvature of field are disposed such that the positions of right and left virtual image surfaces are approximately coincident with each other in an area where the right and left virtual image surfaces overlap each other. With this arrangement, a wide field can be ensured, and moreover, the right and left virtual images can be readily fused because the right and left image surface positions are approximately coincident with each other in an area where the right and left image surfaces overlap each other. Accordingly, the user can perform observation with both eyes without fatigue.
