The present invention relates to a carbazole moiety with an indolo condensation structure, an organic compound in which a hetero condensation ring having a conjugated structure is connected to an indolo carbazole moiety and, as necessary, a different hetero ring is connected to a hetero condensation ring moiety; and to a light emitting diode and an organic light emitting diode using the organic compound. The organic compound of the present invention has excellent thermal stability and color purity. Also, since the organic compound has excellent hole transporting characteristics and/or electron transporting characteristics, a driving voltage rise which may be caused by a delay of charging electrons in a light emitting diode can be prevented. Also, when the organic compound of the present invention is applied, electrons can be charged in balance in an organic material layer constituting the light emitting diode. Light emitting efficiency and a life span of an element can be improved, because light emitting can be induced in not only an interfacial area with an adjacent layer but also all areas of the organic material layer. Since a relatively broad band gap is contained in the organic compound of the present invention, the organic compound can be utilized as a host of the organic layer in the light emitting diode.(110) First electrode(120) Second electrodeCOPYRIGHT KIPO 2018
