Abstract
The invention relates to improving the stability of the lower electrodes in an electroluminescent display employing a thick film dielectric. The invention is an encapsulated electrode comprising an electrode of an electrically conductive metallic film. A layer of encapsulating material is provided on an upper and/or lower surface of the electrode layer. The encapsulating material reduces the risk of the electrode from becoming discontinuous and losing its electrical conductivity.
