Abstract
A method of manufacturing a shaped polymer device comprises forming a planar polymer layer over a substrate which has a lower coefficient of thermal expansion than the polymer layer; and shaping the polymer layer using a laser ablation process. This method uses a substrate with low thermal expansion to limit the expansion of the attached polymer layer when it is being shaped by a laser ablation process. In addition there is provided a lens structure for an *autostereoscopic display device comprising a substantially planar glass substrate and a polymer layer defining a lenticular arrangement provided over the glass substrate.
