Abstract
Abstract A thin film EL displaying apparatus which includes a first thin film EL element, a second thin film EL elements, each element being composed of an EL layer sandwiched between a pair of upper (2, 6) and lower electrodes (12, 16), a first (1) and a second substrates (11) provided respectively with the first (4) and the second thin film EL (14) elements, and an insulating film (3, 13) (5, 15) on the front and rear surfaces of which conductive films for leads are formed. The first (1) and the second substrates (11) are laminated in a manner that the first (4) and the second thin film EL (14) elements face each other and the insulating film (22) are sandwiched therein, and the insulating film (22) is disposed so that one end of each of the conductive film on front and rear surface thereof is brought in contact with and is electrically connected with the upper electrode (2) or lower electrode (12) of the first EL element and the respectively corresponding electrode of the second EL elements, while the other end of each of the conductive films can be connected to an external driving circuit.
