Abstract
A method of producing a lenticular device for an autostereoscopic display apparatus includes providing a substrate having a surface which corresponds in shape to a desired surface profile for the array of lenticular elements, and providing an optical layer mixture of an optically birefringent material and a polymer precursor over the substrate surface. The optical layer is exposed to a stimulus for polymerizing the polymer precursor to have at least a polymer surface layer, thereby enclosing the material between the polymerized material and the surface to define lenticular elements. This method allows a simple polymerization process, forming a single layer, to complete the LC cell formation in the desired lenticular array shape.
