摘要： Disclosed is a polycyclic compound that can be employed in various organic layers of an organic electroluminescent device. Also disclosed is an organic electroluminescent device including the polycyclic compound. The organic electroluminescent device includes a light emitting layer employing the polycyclic compound as a dopant and an anthracene derivative having a characteristic structure and characteristic substituents as a host. The use of the polycyclic compound significantly improves the color purity, luminous efficiency, and life characteristics of the organic electroluminescent device and makes the organic electroluminescent device highly efficient and long lasting.
