Abstract:
An object is to provide a light-emitting element with a favorable lifetime. A light-emitting element which includes a first electrode, a second electrode, and an EL layer and in which the EL layer includes a hole-injection layer and first to fourth layers; the hole-injection layer includes an organic acceptor and is positioned between the first electrode and the first layer; the first layer includes a first hole-transport material; the second layer includes a second hole-transport material and is positioned between the first layer and the third layer; the third layer includes a third hole-transport material; the fourth layer includes a host material and a light-emitting material and is positioned between the third layer and the second electrode; the HOMO level of the second hole-transport material is deeper than the HOMO level of the first hole-transport material; the HOMO level of the host material is deeper than the second hole-transport material HOMO level; the HOMO level of the third hole-transport material is deeper than or equal to the HOMO level of the host material; a difference between the HOMO level of the second hole-transport material and the HOMO level of the third hole-transport material is less than or equal to 0.3 eV; and the second hole-transport material is a triarylamine compound having a structure where a dibenzofuran skeleton or a dibenzothiophene skeleton is bonded to nitrogen of an amine directly or via a divalent aromatic hydrocarbon group.

Claim (Index 52):
An organic compound represented by General Formula (G4) shown below: wherein, in General Formula (G4):\n each of R 1  to R 7  independently represents any one of hydrogen, a saturated hydrocarbon group having 1 to 6 carbon atoms, a cyclic saturated hydrocarbon group having 3 to 6 carbon atoms, and a substituted or unsubstituted aromatic hydrocarbon group having 6 to 18 carbon atoms; \n \u03b1 represents a divalent aromatic hydrocarbon group having 6 nuclear atoms to 18 carbon atoms; and \n Z represents an oxygen atom or a sulfur atom.
