Abstract: A display device for large scale billboard displays comprises a set of image carriers each defining a respective sequence of image frames and each having directional properties such that different image frames are viewable from different viewing directions relative to the image carrier. A support device supports the image carriers such that they together form a composite display and an adjustment device is provided operable to adjust the orientation of the image carriers relative to the support device such that corresponding frames of each image carrier are simultaneously viewable by an observer at a predetermined position relative to the display apparatus. The image carriers may be lenticular members in which lenticular lenses overlay interdigitated strips of image elements.
