Abstract: A display device, in which self-luminous elements are arranged, prevents a leakage current through a common layer, included in the self-luminous elements and disposed throughout its image display area, from causing adjacent pixels to emit unintended light. An organic EL display device has a bank and a light-emitting element layer. The bank is formed on a substrate and is positioned in the border between first and second pixels adjacent to each other. The light-emitting element layer is deposed to spread over the first pixel, the second pixel, and the bank. A first electrode and a second electrode are formed on both sides of the light-emitting element layer and inject electric charges to the light-emitting element layer. A third electrode is formed in contact with the light-emitting element layer in an area overlapping with the bank 106 and absorbs the leakage current.
