Abstract
An organic light emitting diode includes at least one emitting material layer disposed between two electrodes includes a first compound having an azine moiety substituted two cyano groups and a carbazole moiety linked to the azine moiety through a phenylene group, and a second compound of a boron-based fluorescent material and an organic light emitting device including the organic light emitting diode. The excitons generated at the first compound are transferred efficiently to the second compound so that the luminous properties of the organic light emitting diode and/or the organic light emitting device can be improved.
