Abstract
An image display apparatus includes an image generator for displaying an image on a display surface constituted by a plurality of pixels, an illuminator for illuminating the image, and an optical system for guiding a light beam outgoing from the illuminated image to the pupil of the obesever. This causes the observer to observe a virtual image formed by the light beam image. In addition, a angle converter sets a first direction and a second direction substantially perpendicular thereto on the plane of formation of the virtual image and causes the light beam outgoing from each pixel to be incident on the optical system making diverging angles in the first and second directions different.
