Abstract
The method and structure for providing a pair of electrical contact terminals on the back side of an electroluminescent (EL) lamp. The EL lamp has a first conductive layer, a layer of EL material, a first insulating layer, a second conductive layer, a second insulating layer and a film of conductive material, all disposed on a transparent substrate, respectively. The film of conductive material extends around the second insulating layer to come in electrical contact with the first conductive layer. This allows an electrical contact terminal to be established on the film of conductive material, rather than directly on the first conductive layer. The other electrical contact terminal is positioned on the second conductive layer. The second insulating layer serves to electrically separate the two contact terminals.
