More Information
Summary:The invention relates to a new method for producing structured electrodes, especially organic electroluminescent components with a structured electrode such as displays having a structured metal electrode, comprising the followi ng steps: at least two layers (3, 4) are applied on a substrate(1), whereby the first layer (3) is electrically insulated and it is not damaged when the second layer (4) is applied and a defined limit between both layers is preserved, whereby the first layer has a higher solubility rate in a liquid developer than the first layer and the second layer can be structured and cross-linked; the second layer (4) is structured and the structure is transferred to the first layer (3) whereupon the second layer (4) is then cross-linked or the second layer (4) is first structured and cross-linked an d then the structure is transferred to the first layer (3); whereby the second layer has a larger structural width than the first layer and the difference in the structural width of both layers remains after cross-linking; the electro de (6) is deposited on the second layer (4).
