ABSTRACT:
Three component color sub-pixel element areas of red,green and blue, are serially formed in an overall pixel area, on a transparent substrate, and after each individual color sub pixel element formation, a layer of protective transparent material is applied over the individual sub pixel element and the pixel area before formation of the next sub pixel element. The protective layers render the sub pixel elements unaffected by the processing of subsequent sub pixel members where such conditions as high temperature curing, hardening agents or hardening processes are involved, whereby advantages are achieved in manufacturability, reliability, yield, cost, and throughput.
