The present invention relates to an electroluminescent iridium compound represented by the following formula (1) and a display device employing the same as a light emitting dopant, which is pure green in terms of the emission wavelength and also shows a very improved luminous efficiency. It is expected that the lifespan will be significantly improved, which will greatly contribute to improving the lifespan of the full color OLED panel.n n n n n n n n n n Wherein R1 to R12 are the same as or different from each other and are a hydrogen atom or an alkyl group having 2 to 20 carbon atoms, a cycloalkyl group, a haloalkyl group and a halogen group, and n is 1 to 2. |
