Abstract: A multi-indicia display device includes a rigid base plate made up of a plurality of sheets of an electrical insulating material laminated together. Electrodes are mounted on the base plate. One of the electrodes is a metal layer coated on the base plate forming a plurality of separate but identical indicia, each indicia comprising a plurality of sections. Metal layer termination pads are coated on the front and back surfaces of the base plate along one edge thereof. Metal film electrical circuitry is coated on the surfaces of the sheets of the base plate and extend through holes in the sheets to electrically connect the electrodes to the termination pads. A transparent cover is mounted on the base plate and extends over the electrodes.
