Abstract
The invention relates to organic electronic devices containing polycycloolefin planarization layers between the substrate and a functional layer such as a semiconducting layer, dielectric layer, or electrode; to the use of polycycloolefins as a planarization layer on the substrate of an organic electronic device; and to processes for preparing such polycycloolefin planarization layers and organic electronic devices.
