PROBLEM TO BE SOLVED: To obtain a light-emitting body, a light-emitting element and a light- emitting display device that are improved in light-emitting life by preventing corrosion as it has become possible to use a material of low corrosion for the cathode material, as a result of increased emission quantity in the luminous material layer or wide range of selection of the luminous layer and the cathode material. SOLUTION: In the light-emitting body, which is made of an anode and a cathode of which a part is installed opposed to each other through a luminous material layer, an auxiliary electrode is formed through an insulating layer on the opposite face to the face opposed to the cathode through the luminous material layer of the anode. In this light-emitting body, a voltage is impressed between the auxiliary electrode and the cathode so that it may be in the same direction as the direction of the voltage that is impressed between the anode and the cathode. |
