Patent ID: 7431626

Claim:
A method for fabricating an organic electroluminescent display, comprising the steps of: disposing first anodes of red, green and blue unit pixels on a substrate; forming an anode electrode of the red unit pixel by disposing a second anode of the red unit pixel on the first anode of the red unit pixel, each anode electrode of the red unit pixel including a first film having a high reflectivity and a second film for adjusting a work function; forming anode electrodes of the green and blue unit pixels by disposing second anodes of the green and blue unit pixels on the first anodes of the green and blue unit pixels, respectively, each anode electrode of the green and blue unit pixels including a first film having a high reflectivity and a second film for adjusting a work function; disposing respective organic thin-film layers on the anode electrodes of the red, green and blue unit pixels; and disposing a cathode electrode over an entire surface of the substrate; wherein the second anode of at least one unit pixel of the red, green and blue unit pixels has a thickness different from thicknesses of the second anodes of other unit pixels of the red, green and blue unit pixels; and wherein a thickness of the second film of the red unit pixel is in a range of one of 250 to 450 Å and 700 to 750 Å, a thickness of the second film of the green unit pixel is in a range of one of 50 to 150 Å and 200 to 300 Å, and a thickness of the second film of the blue unit pixel is in a range of 50 to 150 Å.
