Abstract:
The invention provides an organic EL device including a pair of electrodes and at least one luminescent layer located between the pair of electrodes, the luminescent layer including a blue phosphorescent material having a luminescence peak in a range of from 420 nm to less than 500 nm, a green phosphorescent material having a luminescence peak in a range of from 500 nm to less than 570 nm, a red phosphorescent material having a luminescence peak in a range of from 570 nm to 650 nm, and a charge-transporting material, the charge-transporting material having a lowest excited triplet energy level (T1) of 2.7 eV or more, and the T1 of the charge-transporting material being higher than the T1 of the blue phosphorescent material by 0.08 eV or more.
