The carbazole derivative possesses an oxadiazole moiety or a quinoxaline moiety as a heteroaromatic ring having an electron-transporting property and a carbazole moiety having a hole-transporting property. The ability of the carbazole derivative to transport both electrons and holes and its large excitation energy larger than a triplet excitation energy of a phosphorescent compound allow the formation of a phosphorescent light-emitting element having well-controlled carrier balance, which contributes to the formation of light-emitting devices and electronic devices that are capable of being driven at a low voltage, have a long lifetime, and consume low power. The detailed structure of the carbazole derivative is defined in the specification.
