ABSTRACT:
An organic electroluminescent display (OLED) device having an anode electrode covered with a solution-coated ultra-thin polymer film (reforming layer) is disclosed. In one embodiment, an OLED device includes a substrate having a first anode electrode formed thereon. The first anode electrode is covered with an ultra-thin polymer film (reforming layer). An organic emission layer is formed over an upper surface of the reforming layer, and a second cathode electrode is formed over the organic emission layer. The reforming layer is made of a material selected from a general polymer that is a soluble polymer, a heat resistant polymer, and a fluorine-based polymer having one or more functional groups. The solution coating methods which may be used to apply the reforming layer include a spin coating method, a doctor blade method, a dip coating method, a roll coating method, a spray coating method, and an ink jet method.
