Abstract
An electroluminescent device having a transparent substrate extending in the lengthwise direction of the device, a transparent conductive layer placed on the back surface of the transparent substrate, a luminescent layer having a width smaller than the width of the transparent conductive layer and being placed on the back surface of the transparent conductive layer, a rear electrode placed on the back surface of the luminescent layer, and at least one buss which is placed on the part of the back surface of the transparent conductive layer having no luminescent layer, has a width smaller than the width of the transparent conductive layer, and is electrically in contact with neither the luminescent layer nor the rear electrode in which the transparent conductive layer, the luminescent layer, the rear electrode and the buss continuously extend in the lengthwise direction of the transparent substrate.
