The present invention relates to novel organic electroluminescent compounds, and organic electroluminescent devices comprising the same. Specifically, the organic electroluminescent compounds according to the invention are represented by Chemical Formula (1):
wherein, total number of carbons in R3-Ar3- and R4-Ar4- is from 21 to 60.
The electroluminescent compounds according to the present invention are green electroluminescent compounds, of which the luminous efficiency and device lifetime have been maximized.
Embodiments of the present invention are directed to a heterocyclic compound and an organic light-emitting device including the heterocyclic compound. The organic light-emitting devices using the heterocyclic compounds have high-efficiency, low driving voltage, high luminance and long lifespan.
