Abstract:
A novel sub-structure of a thick film dielectric electroluminescent display and a thick film dielectric electroluminescent display incorporating the same is provided. The sub-structure comprises a barrier layer between a substrate and a thick film dielectric layer. The barrier layer is chemically inert with respect to the substrate and the thick film dielectric layer and the barrier layer inhibits diffusion of at least one chemical species therethrough. This sub-structure results in a higher capacitance for the thick dielectric layer, which provides higher display luminance and a reduced tendency for dielectric breakdown of the thick dielectric layer. The barrier layer permits for lower cost substrates, such as glass, to be used.
