Claim 10:
11. A light-emitting element comprising:
an anode,
a cathode,
a light-emitting layer comprising a first organic compound, a second organic compound, and an iridium complex between the anode and the cathode,
a first layer on the anode,
a second layer between the first layer and the light-emitting layer,
wherein the first layer comprises an acceptor substance and a third organic compound represented by General Formula (G0),, wherein Ar1 and Ar2 each independently represent a substituted or unsubstituted biphenyl group,
wherein a substituent of the substituted biphenyl group represents any one of an alkyl group having 1 to 10 carbon atoms, an unsubstituted phenyl group or a phenyl group having as a substituent at least one alkyl group having 1 to 10 carbon atoms, an unsubstituted biphenyl group or a biphenyl group having as a substituent at least one alkyl group having 1 to 10 carbon atoms, and an unsubstituted terphenyl group or a terphenyl group having as a substituent at least one alkyl group having 1 to 10 carbon atoms,
wherein Ar3 represents a substituent including a 9-aryl-9H-carbazol-3-yl skeleton,
wherein the aryl group of the 9-aryl-9H-carbazol-3-yl skeleton represents an unsubstituted phenyl group or a phenyl group having as a substituent at least one alkyl group having 1 to 10 carbon atoms, an unsubstituted biphenyl group or a biphenyl group having as a substituent at least one alkyl group having 1 to 10 carbon atoms, an unsubstituted terphenyl group or a terphenyl group having as a substituent at least one alkyl group having 1 to 10 carbon atoms, and
wherein the second layer comprises an aromatic amine compound.
