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 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 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.
