An OLED display having at least first, second, and third differently colored pixels includes a first light emitting layer provided over a substrate for the first and second pixels and a second light emitting layer provided over the substrate for the first, second, and third pixels, wherein the first and second light emitting layers produce light having different spectra, and wherein the light produced by overlapping the first and second light emitting layers has substantial spectral components corresponding to the light output desired for the first and second pixels, and the light produced by the second light emitting layer has substantial spectral components corresponding to the light output desired for the third pixel; and first and second color filters in operative relationship with the first and second pixels.
