Abstract: The present disclosure relates to an organic electroluminescent device comprising an organic electroluminescent compound of high refractive index. According to the present disclosure, an organic electroluminescent device having decreased thickness while implementing a desired color coordinate, or implementing deeper color coordinate in the same device thickness can be provided. As such, the production efficiency of the device can be increased by decreasing the material amount used in the organic electroluminescent device or a broader light-emitting zone can be obtained due to deeper color characteristic in the same device thickness.
