Abstract: An organic electroluminescence device may include a cathode, an anode, and an emitting layer disposed between the cathode and the anode, the emitting layer including: (i) at least one anthracene compound with a dipole moment of >1.0×10−30 Cm (0.3 debye); (ii) at least one organic fluorescent compound with (ii-a) an onset of fluorescence at lower energies than that of (i) and at an energy >2.6 eV, (ii-b) photoluminescence quantum yield >70%, and (ii-c) ionization potential >5.3 eV, as component (2); (iii) at least one organic compound with (iii-a) ionization potential
