ABSTRACT:
Provided are an organic electroluminescent device having high efficiency and a long lifetime, and a production method of the device. The organic electroluminescent device includes an anode, a cathode, and a stacked body interposed between the anode and the cathode and formed by sequentially stacking at least an inorganic compound layer and an organic emission layer, in which the inorganic compound layer has a hole-transporting ability and a work function of the inorganic compound layer changes continuously in a film thickness direction of the inorganic compound layer.
