| Summary: | An image display comprises an image display device for generating a viewable image; and an optical angular selector (290) for selecting an angular range of light to form the viewable image, the optical angular selector having an array of substantially parallel light transmission guides (260) each comprising a light-guiding region (270) to promote propagation of light incident upon the light-guiding region within a range of angles of incidence by refraction and/or total internal reflection and an absorbing material (310) peripherally arranged with respect to the light-guiding region to absorb light incident upon the light-guiding region outside the range of angles of incidence. |
