Abstract
A method for manufacturing a light distribution structure in the form of an optically functional layer includes at least one three-dimensional feature pattern established in a light-transmitting carrier by a plurality of three-dimensional optical features. The method also includes manufacturing a patterned master tool for the at least one three-dimensional feature pattern by a piezoelectric cutting method selected from a fast tool servo method and a stylus engraving method, or by a laser engraving method, and transferring the at least one three-dimensional feature pattern onto the light-transmitting carrier.
