The present disclosure relates to an organic electroluminescent compound, and an organic electroluminescent device comprising the same. It is possible to provide an organic electroluminescent device which can be deposited at a low deposition temperature and/or in which clogging is reduced.

Organic electroluminescent compound and organic electroluminescent device comprising the same

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.

Organic electroluminescent device

The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. The organic electroluminescent compound according to the present disclosure is capable of producing an organic electroluminescent device with reasonably improved color purity and efficiency.

The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. The organic electroluminescent compound of the present disclosure can provide an organic electroluminescent device showing excellence in color purity, solubility, heat stability, driving voltage, current efficiency, and power efficiency, as well as remarkably improved lifespan.
