Abstract

A surface of a substrate which is an outer packaging case is integrated with a decorative film and an EL device. An upper case of the outer packaging case has through-holes through which a transparent electrode layer and a back electrode layer that constitute the EL device are exposed. Contact pins are elastically contacted with the transparent electrode layer and the back electrode layer via the through-holes, and the electrodes are thereby connected to an EL-driving circuit.
