Light-Emitting Element, Light-Emitting Device, Electronic Device, Lighting Device, and Organic Compound

A light-emitting element comprising:

• an EL layer between an anode and a cathode,
• wherein the EL layer comprises a light-emitting layer,
• wherein the light-emitting layer contains a first organic compound, a second organic compound, and a light-emitting substance,
• wherein a combination of the first organic compound and the second organic compound forms an exciplex,
• wherein the first organic compound includes a 6-membered nitrogen-containing heteroaromatic ring and a carbazole skeleton,
• wherein the second organic compound has a hole-transport property,
• wherein a HOMO level of the first organic compound is lower than a HOMO level of the second organic compound, and
• wherein a difference between the HOMO level of the first organic compound and the HOMO level of the second organic compound is less than or equal to 0.4 eV.
