Abstract
A head-mounted image display apparatus capable of displaying an image with dynamic presence even if the observation field angle is not wide, and which is easy to view and unlikely to cause the observer's eye to be fatigued. An image display device (1) is disposed on one side of a projection lens (5') at approximately the focal point of the lens (5'), and a stop (8) is disposed on the other side of the lens (5') at approximately the focal point of the lens (5'), thereby projecting the image of the image display device (1). If the refracting power at the peripheral portion of the projection lens (5') is larger than that at the principal (central) area thereof, the image-formation characteristics of the projected image are deteriorated at the periphery. Consequently, the projected image is blurred at the periphery thereof. Thus, it is possible to project an image in which the edges of the image, which hinder an improvement in dynamic presence, are not clearly displayed.
