The present invention relates to a novel organic electroluminescent compound and an organic electroluminescent device adopting the same, and more specifically, to an organic electroluminescent compound represented by chemical formula 1 below. In the chemical formula 1, ring A and ring B are independently a monocyclic or polycyclic aromatic ring, a monocyclic or polycyclic heteroaromatic ring, a five- or six-membered heteroaromatic ring fused with an aromatic ring, or a monocyclic or polycyclic aromatic ring fused with a five- or six-membered heteroaromatic ring, where the ring A and ring B cannot both be a monocyclic aromatic ring. The organic electroluminescent compound according to the present invention shows good luminous efficiency, and superior material color purity and lifetime characteristics, thereby enabling manufacture of an OLED device with excellent driving time.
