ABSTRACT:
A thin film electroluminescent device constructed on a smooth surface substrate on which a base conductive layer is formed, followed in sequence by an impurity doped barrier layer, an electrically resistive layer and a counterelectrode layer. The impurity doped barrier layer is doped with a material which exhibits electroluminescence.
The impurity doped barrier layer is produced in a controlled oxidation process of the base conductive layer which is alloyed to a minor extent with the impurity material.
