Abstract
A method of fabricating a color organic electroluminescent display involves forming cathode electrodes on a substrate, and forming a first organic semiconductor layer having an electron-injection transporting property on the cathode electrodes. Solutions containing organic light-emitting material that can dissolve portions of the first organic semiconductor layer are patterned on the first organic semiconductor layer. Then, a solvent in the solutions is removed to form regions having second organic semiconductor layers and mixed organic semiconductor layers, wherein the second organic semiconductor layers are formed on the first organic semiconductor layer and are mostly composed of the organic light-emitting material, and the mixed organic semiconductor layers, composed of the organic light-emitting material and material constituting the first organic semiconductor layer, are embedded in the first organic semiconductor layer. Anode electrodes are formed over the first and second organic semiconductor layers. The present invention also provides a color organic electroluminescent display.
