Abstract: A rigid or flexible substrate (1) is comprised of one or several successive thin material layers (2, 9). The first thin material layer (9) is coated onto the substrate (1) and the other layers (2) are applied successively onto the first layer (9). Each thin layer has discontinuous prominent parts arranged in relief on the substrate (1). The thin layer (2, 9) can be electricity conducting. The finished product may be used for display screens or electronic circuits.
