| 摘要 |
The organic electroluminescent element (100) of the present invention comprises, on a substrate (1), electrodes (positive electrode (2) and negative electrode (8)) forming a pair and an organic functional layer (20) having at least an electron transport layer (6) and a light emitting layer (5). At least one of the electron transport layer (6) and the light emitting layer (5) contain semiconductor nanoparticles having a conduction band energy level of -5.5--1.5 ev.
