    摘要： Disclosed is an organic electroluminescent element that has the characteristic of excellent blue chromaticity, achieves a higher level of both external quantum efficiency and driving durability compared to conventional organic electroluminescent elements, and has a low change in chromaticity before and after driving the element. The organic electroluminescent element has a pair of electrodes and a light-emitting layer between said electrodes on a substrate, and the aforementioned light-emitting layer contains: a carbazole compound having a particular structure; and an iridium complex having a particular structure as a blue phosphorescent light-emitting material.
