Organic electro-luminescent device with first and second composite layers
A flexible organic electro-luminescent device is provided, in which a titanium dioxide-silicon dioxide composite layer is formed on the upper and lower surfaces of a transparent plastic substrate. A transparent conductive electrode and an organic luminescent layer are formed in sequence on one of surfaces of the composite layer. The organic luminescent layer is either small molecule luminescent material or polymer luminescent material. Then, a metal electrode is formed on the organic luminescent layer, and a silicon dioxide protecting layer is formed on the metal electrode to enclose the metal electrode and the organic luminescent layer completely. The titanium dioxide-silicon dioxide composite layer and silicon dioxide protecting layer are formed by ion-assisted electron gun evaporation in the temperature lower than 100&deg; C., which does not result in the thermal loading to the small molecule and polymer organic electro-luminescent device.
