Abstract: An electroluminescent device ( 21 ) comprises a first ( 23 ) and a second ( 26 ) electrode layer, at least the second electrode layer ( 26 ) being provided in accordance with a desired pattern and one or more functional layers ( 24, 25 R, 25 G, 25 B), the one or at least one of said functional layers being an electroluminescent layer. In order to pattern the second electrode layer ( 26 ) the EL device ( 21 ) comprises a relief pattern ( 27 ) having one or more overhanging sections ( 29 ). The EL device has means for hindering the transport of fluid along a capillary channel ( 33 ) formed by an overhanging section ( 29 ) and the surface ( 28 a) supporting that section, an example of such means being protrusions ( 35 ) which block and/or reroute the capillary channel ( 33 ). Thus the transport of fluid by the channels ( 33 ) during manufacture of the EL device is hindered and color bleeding between pixels of the EL device and/or leakage current among electrodes of the first electrode layer is prevented.
