In a multi-layered structure of the organic EL diode, a gate insulating layer is formed on a buffer layer. A first insulating layer is formed on the gate insulating layer. An anode is formed on the first insulating layer. Second and third insulating layers commonly having an open portion are sequentially...http://www.google.com/patents/US20040012028?utm_source=gb-gplus-sharePatent US20040012028 - Active matrix organic electroluminescent device simplifying a fabricating process and a fabricating method thereof
