Abstract: Disclosed are an organic light emitting device and a display device using the same in which a light emitting layer includes a host and a plurality of dopants. In the light emitting layer, energy is transferred from a host and other dopants to one dopant by energy transfer system, thus it is possible to increase luminous efficacy of a single color and to increase lifetime of emission.
