| abstract |
The invention provides an organic EL device including a pair of electrodes and at least one luminescent layer between the pair of electrodes, the at least one luminescent layer including at least two phosphorescent materials, an electrically inert material, and a charge-transporting material, the at least two phosphorescent materials being selected from 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, or a red phosphorescent material having a luminescence peak in a range of from 570 nm to 650 nm. The invention also provides a luminescence apparatus including the above organic EL device. |
