An autostereoscopic display comprises an SLM 2 which is controlled to provide an image display and a signal display. A parallax optic 3 has a first portion which cooperates with the image display to form a plurality of viewing windows 16. A second portion 3a of the parallax optic 3 forms first and second images visible to an observer at alternate viewing windows 16 so as to allow the observer to distinguish between desired orthoscopic viewing zones 17, 19, 21 and undesirable viewing positions such as pseudoscopic positions 22-25. <IMAGE> <IMAGE>
