A light-emitting element with low drive voltage, a light-emitting element with high current efficiency, and/or a light-emitting element with a long lifetime are/is provided. Specifically, a light-emitting element with low drive voltage, a light-emitting element with high current efficiency, and/or a light-emitting element with a long lifetime are/is provided by the use of an organic compound with a dibenzo[f,h]quinoxaline skeleton in a light-emitting layer. In a light-emitting element which includes a light-emitting layer containing an organic compound between a pair of electrodes, the organic compound has a 2,3-unsubstituted dibenzo[f,h]quinoxaline skeleton, a hole-transport skeleton selected from a substituted or unsubstituted dibenzothiophene skeleton, a substituted or unsubstituted dibenzofuran skeleton, and a substituted or unsubstituted carbazole skeleton, and an arylene skeleton, and the 2,3-unsubstituted dibenzo[f,h]quinoxaline skeleton and the hole-transport skeleton are bonded through the arylene skeleton. |
