Patent ID: 11944002
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: nan (nan)
Classification: CPC H | IPC H

Claim 9:
10. The organic light-emitting device of claim 9, wherein an absolute value of a lowest unoccupied molecular orbital energy level of the electron transport region of the nth light-emitting unit and an absolute value of a lowest unoccupied molecular orbital energy level of the nth charge generation layer satisfy Equation 2:

∥ELUMO_ETL(n)|−|ELUMO_CGL(n)∥≤0.15 eV.  Equation 2

wherein, in Equation 2, |ELUMO_ETL(n)| is the absolute value of the lowest unoccupied molecular orbital energy level of the electron transport region of the nthlight-emitting unit, and |ELumo_CGL(n)| is the absolute value of the lowest unoccupied molecular orbital energy level of the nth charge generation layer.
