Provided is an organic electroluminescent device. The organic electroluminescent device comprises a first compound having a structure of Formula 1 and a second compound having a structure of Formula 2. Compared to the related art or a device comprising only the first compound or the second compound, a combination of the first compound and the second compound can significantly improve the overall performance of the organic electroluminescent device, such as improved device efficiency, an extended device lifetime and reduced device voltage. Further provided are a display assembly comprising the organic electroluminescent device and a compound composition comprising the first compound and the second compound. |
