ABSTRACT:
A method of making a color filter array on a first substrate having an array of pixels, comprising the steps of: providing a transferable colorant on a second substrate and positioning such transferable layer in transferable relationship with the first substrate; transferring the colorant layer to the first substrate layer; applying a photoresist layer onto the colorant layer; and patterning the photoresist to form selected pads over pixels in the array; and etching the colorant layer through the openings in the patterned photoresist, leaving a portion of the colorant layer over the selected pixels.
