ABSTRACT:
Red phosphorescene compounds and organic electro-luminescence device using the same are disclosed. In an organic electroluminescence device including an anode, a hole injecting layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injecting layer, and a cathode serially deposited on one another, the organic electroluminescence device may use a compound as a dopant of the light emitting layer.
