Abstract
A luminescence cell having a novel structure includes a transparent conductor having a surface on which first and second regions are defined. A first electroluminescence element, including a first organic layer containing an organic luminescence material and a first electrode laminated on the first organic layer, is arranged on the first region. A second electroluminescence element, including a second organic layer containing an organic luminescence material and a second electrode laminated on the second organic layer, is arranged on the second region. The first electrode is physically separated from the second electrode. The first layer is physically separated from the second layer. The first and second organic layers emit light when current flows between the first and second electrodes. The light emitted from the organic layer passes through the transparent conductor and exits the luminescence cell.
