The present invention addresses the problem of providing an organic electroluminescence element which is of a two-side emission type and is transparent when not emitting light but emits light at a uniform brightness and chromaticity from both sides when emitting light, and with which the light emission color can be freely altered. This organic electroluminescence element has, layered in the following order, at least a light-transmitting substrate, a light-transmitting first electrode, an odd number of three or more light-emitting units, a plurality of light-transmitting intermediate electrodes arranged between the light-emitting units, a light-transmitting second electrode, and a light-transmitting sealing substrate, and is sealed by the light-transmitting sealing substrate. The organic electroluminescence element is characterized in that the odd number of three or more light-emitting units include the use of at least two different types of light-emitting unit selected from light-emitting units having light emission colors of blue, green, red, or a mixture thereof, and light-emitting units of different light emission colors are each arranged at positions of symmetry with respect to a light-emitting unit that is arranged in the center. |
