ORGANIC EL ELEMENT, DISPLAY DEVICE, AND ILLUMINATING DEVICE |
| 摘要 |
There is provided an organic EL element including a light emitting unit including at least a plurality of light emitting layers each containing an organic compound and emitting light when a predetermined potential difference is supplied and an intermediate layer that is arranged between the light emitting layers to inject electric charge into the light emitting layers, an anode and a cathode between which the light emitting unit is interposed in a stacking direction and which supply the predetermined potential difference to the light emitting unit, and a potential control mechanism configured to control potential of the intermediate layer in a manner that the potential is set to potential between potential of the anode and potential of the cathode. |
