The invention relates to an organic light-emitting diode comprising a lower electrode (2) and an upper electrode (8), a light-emitting organic layer (5), and at least one doped organic layer (3; 7) that is in contact with one of said electrodes. According to the invention, the level of doping of this organic layer is higher at the interface with the electrode than at the core of said layer (3). This invention makes it possible to very noticeably improve the light output of the diode.
