摘要：
According to one embodiment, there is provided an organic light-emitting diode including an anode and a cathode arranged apart from each other, an emissive layer arranged between the anode and the cathode, a hole injection layer arranged between the anode and the emissive layer and including a polyethylenedioxythiophene, and a hole-transport layer arranged between the hole injection layer and the emissive layer and including a hole-transport material. The emissive layer includes a cathode side first area including a hole transport host material, an electron transport host material and an emitting dopant, and an anode side second area including the hole transport host material and no electron transport host material.
