ABSTRACT:
A method of making a color filter array on a first substrate is disclosed. The method includes depositing and patterning a photoresist layer on the substrate to form openings over selected regions of the substrate; providing a colorant layer having a heat transferable colorant material on a second substrate and positioning the second substrate such that the heat transferable colorant layer is in transferable relationship with but spaced a distance from the first substrate; heating the second substrate sufficiently to cause substantially all of the heat transferable colorant material to transfer across the spaced distance to the patterned photoresist layer on the first substrate; and removing the patterned photoresist layer leaving behind the heat transferable colorant material in the position of the openings over the selected regions of the first substrate.
