Abstract

The present invention relates to an organic EL light emitting element that can suppress deterioration of a light emitting layer and can provide a high light-emission intensity. This organic EL light emitting element includes a light emitting part and a rectifier part connected in series to the light emitting part. Both of the light emitting and rectifier parts include organic thin layers. The electrostatic capacity of the rectifier part is smaller than that of the light emitting part.
