Abstract
An organic light-emitting diode includes an anode and a cathode separately arranged from each other, and an emission layer between the anode and the cathode, the emission layer including a single host material and a light-emitting material, the emission layer including, when the host material has a hole transport property, a doped region on a cathode side to which an electron transport material is doped and an undoped region on an anode side to which an electron transport material is not doped, or the emission layer including, when the host material has an electron transport property, a doped region on an anode side to which a hole transport material is doped and an undoped region on a cathode side to which a hole transport material is not doped.
