ABSTRACT:
The present invention relates to an organic light emitting element comprising: a first light emitting unit comprising a light emitting layer between a pair of electrodes; and a second light emitting unit comprising a light emitting layer between a pair of electrodes. In the organic light emitting element, one electrode of the two pairs of electrodes which is positioned on the outermost side has light reflective properties, and the other electrodes have light transmission properties, while a light-transmitting insulating layer is provided between the first and second light emitting units. The insulating layer is formed in a thickness to prevent light emitted by the light emitting layer of the light emitting unit without the light reflective electrode from interfering with other lights, or formed to have properties of scattering the emitted light. Thus, the interference between the lights emitted by the light emitting layers and the other lights is reduced, so that in the organic light emitting element, the angular dependence of light emission spectrum is small, making it possible to adjust color.
