Beschreibung
Zusammenfassung:	The invention relates to a process for producing a \|enticu\|ar device for an autostereoscopic display apparatus, wherein the \|enticu\|ar device comprises an array of \|enticu\|ar elements having a surface with liquid crystal alignment properties. The process comprises the use of a production mold having a shaped surface which corresponds in negative relief to the desired surface profile for the array of \|enticu\|ar elements, which shaped surface has a nanomorphology represented by grooves. This nanomorphology may be obtained by subjecting the surface of the production mold to abrasion, or by subjecting the surface of a pre-mold, from which the production mold is prepared by molding, to abrasion. The a \|enticu\|ar device obtained from such production mold comprises an alignment layer on the array of \|enticu\|ar elements that is of the same material as the bulk of the \|enticu\|ar device, and not of a different material.
