An optical element such as a rear projection screen for an image display device comprises at least two substantially rigid sheet members each having a first major surface and a second major surface providing a plane of incidence and a plane of emergence, respectively, through which light is transmitted sequentially. A first sheet member comprises a Fresnel lens, and a second sheet member comprises a lenticular lens array on each of the major surfaces thereof. The plane of emergence on the second major surface of the first sheet member includes the Fresnel lens formed of a radiation curable material. A method of making the Fresnel lens is described.
