PURPOSE: An organic electroluminescent element is provided to improve the luminous properties and color purity of blue by using a novel organic electroluminescent material. CONSTITUTION: The organic electroluminescent element comprises a light emitting layer between an electron injecting electrode as a negative electrode and a hole injecting electrode as a positive electrode, wherein a blue light emitting material in the light emitting layer is a compound represented by a general formula 1. In the formula 1, each A1 and A2 is independently substituted or unsubstituted aromatic, heterocyclic, aliphatic group or hydrogen. The light emitting layer further comprises at least two other different materials except the compound of formula 1, in which the content of the compound of formula 1 is 0.1-90 wt%, based on the total weight of the light emitting layer. |
