Organic electroluminescent device and an organic electroluminescent apparatus
An organic electroluminescent device and an organic electroluminescent apparatus are disclosed. The organic electroluminescent device includes a first electrode layer, a first carrier functional layer, a light-emitting layer and a second electrode layer stacked in sequence, wherein a P-doped layer is arranged between the first carrier functional layer and the light-emitting layer. Thus the energy level bending of an interface between the first carrier functional layer and the light-emitting layer is modified, and the hole injection potential barrier at the interface between the two is reduced, thereby effectively reducing the turn-on voltage of the organic electroluminescent device.
