Abstract
An organic electro-luminescence device comprising a substrate, an anode, a light-emitting layer, a cathode and a protection layer. The anode is configured over the substrate. The light-emitting layer is configured over the anode layer. The cathode is configured over the light-emitting layer. The protection layer is configured over the substrate, around the substrate and the anode as well as around the light-emitting layer and the cathode. The protection layer is made from a metallocene based cyclic olefin copolymer.
