An image relay arrangement (20) for use with a curved CRT faceplate (11) to relay a picture to a position in front of the faceplate comprises a first, imaging, microlens array (22), a second, field, microlens array (23) and a third, re-imaging, microlens array (24) which are spaced from one another and have corresponding microlens elements (25, 26, 27). At least one of the first and third arrays is curved with its spacing from the adjacent array varying over its area related to the faceplate curvature. Through this arrangement, the picture at the curved faceplate can be imaged onto a plane where, for example, a lenticular screen is located enabling autostereoscopic displays to be produced.
