摘要：
It is an object of the present invention to provide an organic light-emitting display of high light-emitting efficiency. The organic light-emitting element comprising a board, upper electrode, lower electrode, a plurality of light-emitting units placed between the upper and lower electrodes, and a charge-generating layer placed between a plurality of the light-emitting units, wherein one of the light-emitting units has a layer for emitting monochromatic light and one of the light-emitting units has a layer for emitting polychromatic light, the former unit having an equivalent or lower light-emitting efficiency than the latter unit.
