| 摘要 |
The present invention relates to an organic electroluminescent device, and more particularly, to an organic electroluminescent device, wherein by forming an electrode (cathode) using gadolinium (Gd), which has a low electron injection barrier and can be easily processed, as an electron injection layer in the organic electroluminescent device, the operation voltage of the organic electroluminescent device can be reduced, electron injection can be facilitated to enhance the efficiency of the device, and the stable cathode electrode can also be formed. |
