摘要： A method to ensure uniform deposition of organic layer is disclosed. Since the organic layer is very thin, any deviation from the target thickness will result in visible optical defects. A homogenous layer (275) which exhibits good coating behaviour with organic materials is provided beneath the organic layer. By covering the metal interconnects (205), the adverse effect on the uniformity of the polymer layer is reduced or prevented.

摘要： A novel electroluminescent device is produced by printing an electroluminescent organic layer with a planographic printing process. Organic LEDs are formed in that the organic material is printed onto patterned electrodes on a substrate and the organic material is contacted by metallic electrodes formed following the printing process. Any of the accurate planographic printing processes is suitable, such as pad printing, offset printing, dry offset printing, letterpress printing, and intaglio printing. The resulting device may be a flat panel display with only a few discrete display fields or an intricate, pixeled multi-color or full-color electroluminescent display device or a light source.
