Abstract

An electroluminescent device (51) comprises a partitioning relief pattern having overhanging sections (13) for partitioning an electrode layer of the electroluminescent device (51) into a plurality of independently addressable electrode segments (11a, 11b, 11d). The overhanging section (13) is bent at predetermined positions (13b, 13c, 13d, 13e). The bends thus formed are rounded and/or beveled in order to reduce the risk that electrode segments (11a, 11b, 11d) are inadvertently connected via a second electrode layer segment present on top of the overhanging section (13).
