Abstract
A display comprises: a single-view image display panel (6); and a parallax optic (8) disposed over a display face of the image display panel for restricting the angular spread of light output from the display face of the image display panel. This enables light to be concentrated in a desired viewing angle range (66), and avoids a user (56) seeing unwanted reflections that may occur as a result of a greater viewing angle range (64) if the parallax optic (8) is not provided. The display may be used, as an example, in a motor vehicle to prevent unwanted reflections from the windscreen (62) of the vehicle.
