Abstract: The present disclosure relates to an organic electroluminescent element, and more particularly to an organic electroluminescent element including a novel boron-based organic compound and anthracene-based organic compound in one or more organic layers included in the organic electroluminescent element. The present disclosure may provide an organic electroluminescent element, which is prevented from deterioration in color characteristics and has characteristics such as long lifetimes, as a result of using a host material having a specific structural formula despite having high polarity.
