An organic light emitting device is disclosed that may include a first electrode, a hole injecting layer, a hole transporting layer, an emitting layer, and a second electrode, wherein a ratio of thickness between the hole injecting layer and the hole transporting layer is in a range of about 1:1 to about 1:10. Since the relative thicknesses of the hole injecting layer and the hole transporting layer are controlled, leakage current in the organic light emitting device decreases. As a result, the electrical characteristics and the testability of the organic light emitting device may be improved.
