Abstract: PROBLEM TO BE SOLVED: To eliminate a useless current leaking in a reversed direction or the like and to heighten rectification property, by conducting a predetermined display by means of a potential difference at crossing parts of a plurality of negative electrodes and a plurality of positive electrodes and by forming the negative electrodes of a material mainly composed of aluminum. SOLUTION: An ITO transparent electrode 5 (a positive electrode), a hole transport layer 4, an electron transport layer 2, and an electrode layer 1 (a negative electrode) are laminated in order on a transparent substrate 6 such as glass. In the case that an organic EL element 20 is a simple matrix, one picture element of the element 20 is formed at each of crossing parts of the electrode 5 and the electrode 1 on one and the same substrate 6, which is, as a circuit, made equivalent to a case where one diode is connected to each of these crossing parts. A predetermined display is conducted by means of a potential difference between the two electrodes at each of the crossing parts while the electrode 1 is formed of a material mainly composed of aluminum. Forward rectification property at the crossing parts being thereby improved, an increased ratio of backward resistance to forward one preventing a backward current from flowing, a leakage current being reduced, and performance can be improved.
