Abstract

An organic electric element includes a first electrode, a second electrode, and an organic material layer between the first electrode and the second electrode. The organic material layer includes a light-emitting layer, a hole transport layer between the first electrode and the light-emitting layer, and a plurality of emission-auxiliary layers between the light-emitting layer and the hole transport layer. The plurality of emission-auxiliary layers include a first emission-auxiliary layer adjacent to the hole transport layer and a second emission-auxiliary layer adjacent to the light-emitting layer. Each of the first emission-auxiliary layer and the second emission-auxiliary layer is independently formed of one type of a compound without additional doping. The first emission-auxiliary layer includes a compound represented by Formula 1 or Formula 2, and the second emission-auxiliary layer includes a compound represented by Formula A-4-1 or Formula A-4-2.
