Organic electroluminescent device and a method of manufacturing thereof

摘要

An electroluminescent device ( 1 ) has a relief pattern ( 17 ) comprising overhanging sections ( 13 ) for patterning an electrode layer ( 11 ) of the device ( 1 ). In order to prevent the take up and transport of fluid, from which a functional layer ( 7, 9 ) is obtainable, along the capillary channels ( 23 ) formed by the overhanging sections ( 13 ), the relief pattern ( 17 ) comprises accompanying sections ( 15 ) which are positioned at distance of the overhanging sections ( 13 ) and between the sections ( 13 ) and the electroluminescent areas ( 21 ) comprising the functional layers ( 7, 9 ). A method of manufacturing the EL device ( 1 ) comprises depositing the functional layer or layers ( 7, 9 ) by means of a wet deposition method such as inkjet printing.
