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.

A display unit has first and second substrates, a liquid crystal display, an organic electroluminescent display, a reflector and a plurality of common electrodes. The liquid crystal display is located between the substrates. The organic electroluminescent display is located between the first substrate and the liquid crystal display. The organic electroluminescent display has an organic electroluminescent layer. The reflector reflects a light that passes through the organic electroluminescent layer and the liquid crystal display. The common electrodes are commonly used for both displays. Pixels are formed on both displays. In each display, each pixel is located at a position that corresponds to one of the common electrodes.

Display unit

A color display improves the contrast of a shown image without decreasing an open area ratio. A color electroluminescent display of the present invention has electroluminescent elements provided on a black insulation layer. A predetermined space exists between each adjacent pair of the electroluminescent elements. Filter elements are provided on the electroluminescent elements. The interface between each adjacent pair of the filter elements extends along the thickness direction of the color electroluminescent display and is aligned with one of the spaces.
