摘要： An image display apparatus, e.g., a head-mounted image display apparatus, which uses a compact optical system and yet has minimal aberrations and a large exit pupil diameter. An image displayed on a liquid crystal display device (2) is projected as an enlarged image in a user's eyeball by a convex lens (3). Prism arrays (13 and 14) having the same vertex angle are disposed in parallel to each other between the convex lens (3) and an exit pupil (6) so that the array directions coincide with each other. A parallel beam of light passed through the convex lens (3) has a pupil diameter (a) determined by the numerical aperture of an illumination system (1). The parallel beam first enters the prism array (13) and separates into light beams traveling in four different directions by the prism refracting action. These light beams then enter the prism array (14), which has the same vertex angle as that of the prism array (13). Consequently, the light beams are refracted again to become parallel to each other. As a result, the beam diameter (a) of the light before entering the prism array (13) enlarges to a beam diameter (b) after the light has emanated from the prism array (14). Accordingly, the effective pupil diameter enlarges.

摘要： 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.
