Abstract
A method for manufacturing a structured optical device () starts with a substrate (), on which is coated an alignment layer () and a liquid crystal polymer network layer (). One of these layers can be created as a coating using a conventional technique. The other layer, either in a first step the alignment layer or in a second step the liquid crystal polymer network layer, is jet printed. The invention advantageously enables the making of a patterned liquid crystal polymer network which can be personalized upon manufacturing.
