Method of producing a display having a patternable conductive traces

A method of fabricating a display having light sensitive conductive traces and a color filter array, comprising the steps of:

• a) providing first and second light sensitive layers respectively over both sides of an electrically sensitive light modulating layer, the first and second light sensitive layers being conductive and patternable;
• b) patterning the first light sensitive layer to a first wavelength of radiation to form first conductive traces;
• c) patterning the second light sensitive layer to a second wavelength of radiation to form second conductive traces
• d) providing a light blocking layer have a soluble dye over one of the conductive traces and light-sensitive dye forming layers over the light blocking layer;
• e) exposing light-sensitive dye forming layers to separable wavelengths of light to selectively sensitize a color filter precursor on the display;
• g) processing the exposed light-sensitive dye forming layers to provide a color filter array;
• and
• f) removing soluble dye from the light-blocking layer.
