A method of making an OLED display having at least first, second, and third differently colored pixels includes providing a first light-emitting layer over a substrate for the first and second pixels and a providing a second light-emitting layer over the substrate for the third pixel wherein the first and second light-emitting layers produce light having different spectra and the light produced by the first light-emitting layer has substantial spectral components corresponding to the light output desired for the first and second pixels, and forming a first color filter in operative relationship with the first pixel and no color filter corresponding to the second pixel.
