ABSTRACT:
Provided are an anthracene derivative compound represented by Formula 1 below and an organic light-emitting device using the same:whereinAr1and Ar2are each independently aromatic groups, R1and R2are each independently substituent groups, and X is a heteroatom or substituted heteroatom. The use of the anthracene derivative compound enables to produce an organic light-emitting device with better driving voltage, brightness, efficiency, and color purity.
