<p>PROBLEM TO BE SOLVED: To provide a display panel having high durability and a long lifetime by having a corrosion resistant metal having corrosion resistance higher than that of a metal electrode in plural electrode leading parts connected to plural metal electrode ends formed on a substrate. SOLUTION: Plural positive electrodes 5 respectively formed of a transparent conductor, a light emitting layer 7 made of the organic EL material, and plural negative electrodes made of the metal material such as Al and arranged opposite to the positive electrodes 5 are formed on a glass substrate 3. A part of a negative electrode leading part 11 made of the material different from the material of the metal electrode 9 is positioned outside of a sealing can area, and works as a connecting terminal to a drive circuit. All the metal electrodes 9 are sealed in the sealing can area. Desirably, the metal electrode has electrical resistivity lower than that of the electrode leading part and the metal electrode desirably includes at least any one of aluminum, copper and gold, and the electrode leading part is formed with the double layer structure of an ITO layer (indium and titanium oxide layer) and a chrome layer formed on the ITO layer.</p> |
