PROBLEM TO BE SOLVED: To provide an organic light-emitting element having stable performance in the atmosphere.SOLUTION: The organic light-emitting element includes: a first organic compound layer disposed between a cathode and a light-emitting layer; and a second organic compound layer disposed between the light-emitting layer and the first organic compound layer and being in contact with the first organic compound layer. The first organic compound layer has a first organic compound, and the second organic compound layer has a second organic compound. The first organic compound is a viologen compound represented by general formula [1], and the second organic compound is an organic compound different from the viologen compound. |
