Abstract
An EL lamp has a perimeter that is beveled such that the rear electrode is smaller in area than the front electrode due to the bevel. The lamp is made by placing an EL panel on a concave die with the rear electrode in contact with the die and shearing the edge of the lamp at an acute angle between 30.degree. and 60.degree., preferably 45.degree.. For circular or nearly circular lamps, the entire perimeter of the lamp can be cut in a single stroke.
