Abstract

Disclosed are an anthracene derivative with a specific structure and an organic electroluminescent device including the anthracene derivative. The organic electroluminescent device includes a light emitting layer employing the anthracene derivative as a host compound and a polycyclic aromatic derivative with a specific structure as a dopant compound. The use of the host and dopant compounds allows the organic electroluminescent device to have a long lifetime and significantly improved low-voltage characteristics.
