Abstract: In a method of manufacturing an organic electroluminescent display, a substrate, in which a plurality of pixel areas is defined, is prepared, and first electrodes are formed in the pixel areas. Organic light emitting layers are formed on the first electrodes and a second electrode is formed on the organic light emitting layers. Resonant controllers are formed to control a resonant distance between each of the first electrodes and the second electrode. The resonant controllers are formed by providing solutions to at least two pixel areas, which emit lights having different colors, with a same amount in a one-to-one correspondence, and removing a solvent from the solutions. The solutions have different concentrations from each other.
