(57) [Abstract] [Purpose] It is an object to provide a high-performance electroluminescent element having a long emission life. In an electroluminescent device having an organic layer between a hole injecting electrode 2 and an electron injecting electrode 5, a rhodamine metal complex, a chromone metal complex, or a material for the organic layer, or An azomethine metal complex is used, or an azomethine metal complex is used in the electron transport layer. |
