ABSTRACT:
A thick film luminescent device includes a substrate which supports a first and second electrode, the electrodes being separated from each other by an electroluminescent layer. Each of the electrodes has a conductor connected thereto including a terminal portion remotely situated from the electrode. An insulated layer opposite the substrate covers all of the conductors and electrodes except for the terminal portions. A conductive shielding layer is provided which is substantially coextensive with the insulated layer, the shielding layer including a terminal portion adapted to be connected to a suitable ground so as to prevent signal interference between the thick film luminescent device and adjacent electronic circuitry.
