The present invention provides an organic electroluminescent element comprising a light emitting layer having a good charge transfer characteristic, capable of easily injecting the charge into the light emitting layer, and a method for producing an organic electroluminescent element with a stable quality. The object can be solved by an organic EL element provided with a substrate plate having a first electrode, a substrate plate having a second electrode, and a light emitting layer comprising a liquid crystalline organic semiconductor material and a light emitting material and disposed between the substrate plates, wherein an organic thin layer having a dipole moment for reducing a charge injection barrier between the electrodes and the light emitting layer is formed between the first electrode and the light emitting layer and/or between the second electrode and the light emitting layer. The organic EL element is produced by forming an organic thin layer having a dipole moment on a substrate plate having a first electrode and/or a substrate plate having a second electrode, disposing the substrate plates so as to face the electrodes each other while forming a gap portion, and injecting a liquid crystalline organic material for a light emitting layer to the gap portion between the electrodes to form a light emitting layer. |
