PURPOSE: A heterocyclic compound, a light emitting diode, a light emitting device, an electronic device, and a lighting device are provided to ensure high light emitting efficiency using a compound which is conjugated to a dibenzo quinoxaline ring. CONSTITUTION: A heterocyclic compound contains a dibenzo quinoxaline ring, a first hole transport skeleton, a second hole transport skeleton, and an aromatic hydrocarbon group. The heterocyclic compound is conjugated with the dibenzo quinoxaline ring, and the first hole transport skeleton. The second hole transport skeleton is conjugated with the aromatic hydrocarbon group. The aromatic hydrocarbon group is conjugated at the second site of the dibenzo[f,h] quinoxaline ring. A light emitting diode contains a pair of electrodes and a layer containing an organic compound. The layer containing the organic compound contains a heterocyclic compound. A light emitting device, an electronic device, and a lighting device contain the light emitting diode. |
