Abstract
An organic EL display device includes first and second electrodes, a light-emitting layer interposed between the first and second electrodes, an organic soluble derivative layer arranged between the first electrode and the light-emitting layer, wherein the organic soluble derivative layer prevents impurities from being diffused to the light-emitting layer, and a small molecular hole transporting layer between the organic soluble derivative layer and the light-emitting layer.
