ABSTRACT:
An organic electroluminescent display has: anode electrodes of R, G and B unit pixels formed separate from each other on a substrate; organic thin-film layers of the R, G and B unit pixels formed on the anode electrodes; and a cathode electrode formed over an entire surface of the substrate. The anode electrode of at least one unit pixel, among the R, G and B unit pixels, has a thickness different from anode electrodes of the other unit pixels. The anode electrode of each of the unit pixels comprises a first film having a high reflectivity and a second film for adjusting a work function. The second film of at least one unit pixel, among the unit pixels, has a thickness different from the second films of the other unit pixels. The second film of the R unit pixel is thicker than the second films of the other unit pixels.
