Abstract:
A light-emitting element includes an anode, a cathode, a luminescent layer disposed between the anode and the cathode and containing a host material, a first luminescence-assisting layer disposed in contact with the luminescent layer between the anode and the luminescent layer and containing a first luminescence-assisting material having characteristics the same as or similar to the host material, and a second luminescence-assisting layer disposed in contact with the luminescent layer between the cathode and the luminescent layer and containing a second luminescence-assisting material having characteristics the same as or similar to the host material. The luminescent layer and the first luminescence-assisting layer each contain a high-molecular-weight material.
