Classification: CPC H | IPC H

Claim 7:
8. The organic light-emitting device of claim 7, wherein the absolute value of the lowest unoccupied molecular orbital energy level of the mth electron transport region and the absolute value of the lowest unoccupied molecular orbital energy level of the host satisfy Equation 1:

∥ELUMO_ETL(m)|−|ELUMO_Host∥≤0.2 eV.  Equation 1

wherein, in Equation 1, |ELUMO_ETL(m)| is the absolute value of the lowest unoccupied molecular orbital energy level of the mth electron transport region, and |ELumo_Host| the absolute value of the lowest unoccupied molecular orbital energy level of the host.
