Organic electroluminescent device
摘要:
An organic electroluminescent device including, a hole-transporting layer, an emitting layer and an electron-transporting layer in this order between an anode and a cathode, an emission spectrum having emission peaks when applying current for emission, the intensity (ID) of the maximum emission peak among the emission peaks and the intensity (IO) of another emission peak at a shorter wavelength than the wavelength of the maximum emission peak among the emission peaks satisfying the following formula (A), IO/ID
