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, 25R,25G,25B), 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 (28a) 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.
