A ridged reflector (,) permits operation of an optical display device (,) in ambient light, which may be supplemented by artificial back-lighting. The ridged reflector (,) for use in an optical display (,) includes a transparent polymeric layer (,) having a ridged surface (,). The ridged surface (,) includes a series of ridges (,). Each of the ridges (,) has a first face (,) and a second face (,) preferably intersecting the first face (,). A reflective layer (,) overlies the first face (,) of each of the ridges (,). The second face,(,) is generally light-transmissive and substantially free of a reflective layer (,). The ridged surface (,) has an opposite surface (,) opposite the ridged surface (,). The second face (,) of each of said ridges (,) allows optical communication with the opposite surface (,) for optional back-lighting of the optical display device.
