摘要 |
A light-emitting element emitting phosphorescence and having high emission efficiency, in which a property of injecting holes to a light-emitting layer is increased, is provided. The light-emitting layer of the light-emitting element includes a first organic compound represented by the following general formula (G1) and a second organic compound which is a phosphorescent compound. The difference between the HOMO level of the first organic compound and the HOMO level of the second organic compound is lower than or equal to 0.3 eV. |
