An EL lamp has a perimeter that is beveled and said rear electrode is smaller in area than said front electrode due to said 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. The angle is between 30 DEG and 60 DEG and is preferably 45 DEG . The die has a radius of curvature that is 50-150 times the thickness of the panel to prevent deformation of the panel. For circular or nearly circular lamps, the entire perimeter of the lamp can be cut in a single stroke.
