摘要:
An organic electroluminescence device includes an anode, an emitting layer, an electron transporting zone and a cathode in sequential order. A blocking layer is provided in the electron transporting zone adjacently to the emitting layer. The blocking layer contains a fused hydrocarbon compound and at least one compound selected from an electron-donating dopant and an organic metal complex that contains an alkali metal. A triplet energy of the fused hydrocarbon compound is 2.0 eV or more.
