ABSTRACT:
A method of making a color filter array on a first substrate comprising the steps of: providing at least one transferable colorant layer on a second substrate and positioning such transferable layers in transferable relationship with but spaced a distance from the first substrate; and heating the second substrate sufficiently to simultaneously transfer the colorant materials from the heat transferable colorant layers to the first substrate. Unwanted colorant is then removed by a lift-off process, by chemical mechanical polishing, or by etching, leaving behind the colorant materials in the position of the openings over selected regions.
