Abstract:
The present application relates to an organic electroluminescent device (OLED) which has an emitting layer comprising a compound having a small difference between the energies of the S1 and T1 states, and in which certain conditions apply to the HOMO and LUMO energy levels of the emitting layer and the layers between the anode and the emitting layer.
