    摘要: It is an object to provide a light-emitting element with high luminous efficiency by using a hole transporting substance with a sufficiently high T1 level. Further, it is another object to provide a light-emitting device and an electronic appliance with low power consumption by using a hole transporting substance with a sufficiently high T1 level. The present invention provides a light-emitting element which has a first layer containing a spiro-9,9′-bifluorene derivative in which one amino group is combined and a second layer containing a phosphorescent compound between an anode and a cathode.
