| abstract |
The present invention relates to an aromatic amine derivative having a specific structure and an organic electroluminescence element in which at least one or more organic thin film layers including a light-emitting layer are sandwiched between the cathode and the anode, wherein the organic thin film At least one layer of the layer, especially the positive hole transport layer, contains the aromatic amine derivative as a single component or a component of a mixture, thereby providing a device that is difficult to crystallize molecules and improves the yield when manufacturing an organic electroluminescent element. , Long-life organic electroluminescent components. |
