Abstract
A composite substrate includes a substrate, an electrode formed on the substrate, a first dielectric layer of thick film dielectric formed on the electrode, a second dielectric layer formed on the first dielectric layer by a solution coating-and-firing technique, and a buffer layer formed below and/or within the first dielectric layer. The composite substrate keeps the thick-film dielectric layer fully insulating and enables functional thin films formed thereon such as a light emitting layer to perform stable operation, especially stable light emission. An EL panel using the same and a method for preparing the same are also provided.
