1. A light-emitting element comprising:
a pair of electrodes;
a light-emitting layer between the pair of the electrodes; and
a hole-injection layer between the light-emitting layer and one electrode of the pair of the electrodes,
wherein the light-emitting layer comprises a light-emitting material and a host material,
wherein the light-emitting material comprises at least one amino group and any of a substituted or unsubstituted naphthobisbenzofuran skeleton, a substituted or unsubstituted naphthobisbenzothiophene skeleton, and a substituted or unsubstituted naphthobenzofuranobenzothiophene skeleton,
wherein the one amino group bonds to any of a substituted or unsubstituted dibenzofuranyl group, a substituted or unsubstituted dibenzothiophenyl group, and a substituted or unsubstituted carbazolyl group,
wherein the light-emitting material exhibits blue light emission, and
wherein the hole-injection layer comprises a first organic compound having any of a halogen group and a cyano group.
