Abstract
The present disclosure relates to an organic element, a display panel and a display device. The organic light emitting element includes: a first electrode; a hole layer disposed on the first electrode; a light emitting layer including a first light emitting portion, a second light emitting portion and a third light emitting portion; an electron layer on the light emitting layer; and a second electrode disposed on the electron layer. An energy level difference between the hole layer and the first light emitting portion and/or an energy level difference between the first light emitting portion and the electron layer is greater than or equal to a first threshold, so that a turn-on voltage difference between the first light emitting portion and the second light emitting portion is smaller than a second threshold.
