ABSTRACT:
An improved hermetic seal means for use in an electroluminescent display device for joining the protective cover sheet (glass) over the base substrate. The base substrate has typically deposited thereon multiple thin film layers. The hermetic seal comprises an electrically insulative thin film layer disposed over the conductive thin film leads associated with the multiple thin film layers, and metallic solder means over the insulative thin film layer to provide a bond between the cover sheet and base substrate.
