ABSTRACT:
A thin film EL displaying apparatus includes a first thin film EL element and a second thin film EL element. Each element is composed of an EL layer sandwiched between a pair of upper and lower electrodes, a first and a second substrates provided respectively with the first and the second thin film EL elements, and an insulating film on the upper and lower surfaces on which conductive films for leads are formed. The first and the second substrates are laminated in a manner that the first and the second thin film EL elements face each other and the insulating films are sandwiched therein. The insulating film is disposed such that one end of each of the conductive films on upper and lower surface thereof is brought in contact with, and is electrically connected to the upper electrode or lower electrode of the first EL element and the respectively corresponding electrode of the second EL elements. The other end of each of the conductive films can be connected to an external driving circuit.
