Method of manufacturing an organic electroluminescent device

An organic electroluminescent (EL) device ( 1 ) has at least one EL element ( 10 ) comprising an organic electroluminescent layer ( 6 ) and a relief pattern ( 7 ). The relief pattern serves to contain the fluid layer from which the EL layer ( 6 ) is obtained. In order to counteract the adverse effec...

Zusammenfassung:	An organic electroluminescent (EL) device ( 1 ) has at least one EL element ( 10 ) comprising an organic electroluminescent layer ( 6 ) and a relief pattern ( 7 ). The relief pattern serves to contain the fluid layer from which the EL layer ( 6 ) is obtained. In order to counteract the adverse effect the relief pattern may have on the service life of the EL device, the EL device is provided with an EL layer ( 6 ) substantially uniform in thickness. In addition, a matrix or segmented display device comprising a plurality of EL elements ( 10 ) is provided. In a preferred method of manufacturing the EL device the fluid layer is deposited by means of ink-jet printing, dispensing or spin-coating.
