ABSTRACT:
A material for organic electroluminescence device with specific structure having poor symmetry. An an organic electroluminescence device comprising a cathode, an anode and an organic thin film layer which is sandwiched between the cathode and the anode and comprises at least one layer, wherein at least one layer in the organic thin film layer contains a material for the organic electroluminescence device described above. An organic electroluminescence device with excellent efficiency of light emission, without pixel defects and which is superior in heat resistance is obtained.
