Abstract:
A novel light-emitting element material is provided. Alternatively, a light-emitting element material capable of simplifying a process for manufacturing a light-emitting element is provided. Alternatively, a light-emitting element material capable of reducing the cost for manufacturing a light-emitting element is provided. Alternatively, one embodiment of the present invention provides a light-emitting element material capable of achieving a light-emitting element having favorable emission efficiency. A light-emitting element material including an organic compound which includes a first skeleton having a carrier-transport property and a second skeleton having a light-emitting property in one molecule and in which the molecular weight is less than or equal to 3000, is provided.
