To provide a light-emitting device not only including a light-emitting layer in which energy is efficiently transferred from a host material to a guest material but also having high reliability. The light-emitting device not only includes a light-emitting layer in which the T1 levels and the S1 levels of a host material and a guest material fall within certain ranges so that energy can be efficiently transferred from the host material to the guest material and but also has improved reliability.
Provided is a novel organic compound or a light-emitting element material. The organic compound includes an aromatic hydrocarbon group having 6 to 100 carbon atoms in the 5-position of benzo[a]carbazole and an aromatic hydrocarbon group having 6 to 30 carbon atoms in the 11-position thereof. The light-emitting element material includes the organic compound.
