ABSTRACT:
An electroluminescent lamp conductive layer structure for contacting with a connector. The structure includes first side and second side conductive layers. The first-side conductive layer extends on an isolation layer structure over an electrode so as to be electrically isolated from the electrode by the isolation layer. The first-side conductive layer has a first contact portion which contacts the connector. The first contact portion extends over a first region of a leveled portion of the isolation layered structure. The second-side conductive layer is electrically connected to the electrode. The second-side conductive layer is spaced from the first-side conductive layer. The second-side conductive layer has a second contact portion which contacts the connector. The second contact portion extends over a second region of the same leveled portion of the isolation layer so that at least the first and second contact portions have the same level as each other. The respective layered structures between the substrate and the contact portions are identical.
