摘要:
It is an object of the present invention to provide an electron injecting composition which is excellent in light-transmitting property, safety and electron injecting property, and a light emitting element and a light emitting device using the electron injecting composition. The electron injecting composition according to the present invention includes a benzoxazole derivative indicated by a general formula (1) and an electron donating organic compound; (where Ar is an aryl group, each of R1 to R4 represents hydrogen, halogen, a cyano group, an alkyl group having 1 to 10 carbon atoms, a haloalkyl group having 1 to 10 carbon atoms, an alkoxyl group having 1 to 10 carbon atoms, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group).
