Abstract
The present invention relates to the following polycyclic aromatic derivative organic light emitting compound, and an organic light emitting device employing same as a dopant compound of a device light emitting layer. The organic light emitting device according to the present invention comprises a polycyclic aromatic derivative compound as a dopant compound in a light emitting layer, and also, at the same time, employs, alongside the dopant compound, an anthracene derivative compound having a characteristic structure in the light emitting layer by combining same as a host. Accordingly, the organic light emitting device according to the present invention has excellent color purity, high luminous efficiency, and a remarkably improved long life, and thus can be usefully used in various display devices.
