An image display comprises: a display device having an image output surface at which an image is displayed as a spaced array of pixel elements; an image guide () coupled to the image output surface of the display device and comprising a plurality of light transmission guides () each having an input end and an output end, the input ends of the light transmission guides being arranged relative to one another so that groups of one or more light transmission guides receive light from respective groups of one or for a cluster comprising at least a subset of the light transmission guides (): at the outer periphery of the cluster, the input ends of the light transmission guides are constrained against expansion by a frame formed of a material having thermal expansion properties which are substantially similar to the thermal expansion properties of the image output surface.

Image display device

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.
