Patent ID: 8178217

Claim:
A light-emitting element comprising: a pair of electrodes; a triazole derivative between the pair of electrodes, a light-emitting substance between the pair of electrodes; and a substance in which a hole-transporting property is higher than an electron-transporting property, wherein the substance is provided between the pair of electrodes, wherein the triazole derivative is represented by a general formula (G1) and Ar 3 is bonded with a 9H-carbazol-9-yl group which is represented by a general formula (G2), wherein Ar 1 and Ar 2 each represent an aryl group or a heteroaryl group, wherein Ar 1 represents an unsubstituted phenylene group, a pyridin-2,5-diyl group, or a pyridin-2,6-diyl group, wherein R 1 to R 8 each represent hydrogen, an alkyl group, an alkoxy group, or an aryl group, and wherein the number of the carbazole skeleton included in the triazole derivative is one.
