Abstract
Processes are provided for depositing multiple color filter materials on a substrate to form color filters. In a first process, the surface characteristic of a substrate is modified by radiation so that a flowable form of a first color filter material will be deposited on a first area, and converted to a non-flowable form. A second color filter material can then be deposited on a second area of the substrate. In a second process, first and second color filter materials are deposited on separate donor sheets and transferred by radiation to separate areas of the substrate. A third process uses flexographic printing to transfer the first and second color filter materials to the substrate.
