1. An image display apparatus comprising:
an original image forming unit including a plurality of image forming regions configured to form an identical image in each of the image forming regions; and an optical system including a plurality of optical elements arranged in a one-to-one correspondence with image forming regions, wherein each of the plurality of optical elements is configured to convert a light beam from a region corresponding to the region among the image forming regions to a parallel light beam and guide the parallel light beam onto a viewer's eye, wherein an exit pupil diameter D of the optical system satisfies
D>2*[R*sin(ω)−Rp*cos(ω)] where ω is a maximum angle of view in the image display apparatus, Rp is a radius of a pupil of the viewer's eye, and R is a distance from the rotational center of the eyeball to the pupil of the viewer's eye.
