An image display apparatus includes an image forming apparatus 30, an optical element 40 that is arranged in front of a face of an observer 80, and a movement control apparatus. When a region 85 situated on the side of the ear of the observer 80, as viewed from the optical element 40, is referred to as a region situated behind the optical element, the image forming apparatus 30 is arranged in the region situated behind the optical element. An image exiting the image forming apparatus 30 obliquely enters the optical element 40 from the region situated behind the optical element, and is reflected off the optical element 40 to reach a pupil 82 of the observer 80. When there is a change in the position of the pupil 82 of the observer 80, the optical element 40 is moved using the movement control apparatus, and the position of the image exiting the image forming apparatus 30 is controlled using the movement control apparatus. |
