摘要:
An organic electroluminescent element includes a light-emitting layer between an anode and a cathode. The light-emitting layer contains a phosphorescent light-emitting organic metal complex and at least one host compound. The difference in relative dielectric constant between the host compound and the phosphorescent light-emitting organic metal complex is 0 to −0.5, and the difference in dipole moment between the host compound and the phosphorescent light-emitting organic metal complex is 0 to −5.5 debye.
