| 1. An organic electroluminescent element comprising:
a plurality of luminescent regions each having a first electrode that is transparent and a second electrode that is opaque,
each luminescent region having an organic layer that is sandwiched between the first electrode and the second electrode for
emitting light, wherein the first electrodes are physically adjacently located; and
an insulation portion which is provided between the first electrodes and is in physical contact with the second electrode,
wherein the plurality of luminescent regions are electrically and serially connected;
wherein the second electrode of one of the luminescent regions is electrically connected to the first electrode of the electrically
adjacent luminescent region, and
wherein the insulation portion has a scattering means that scatters the light emitted from the organic layer.
