Abstract

An organic light-emitting element according to the present invention employs a polycyclic aromatic derivative compound in a light-emitting layer inside the element, and further comprises a capping layer. Thus, the organic light-emitting element can be made highly efficient and can be useful for a device selected from among a flat panel display device, a flexible display device, a monochrome or white flat panel lighting device, and a monochrome or white flexible lighting device.
