Abstract
A means to fabricate a color filter for use in a display, such as a liquid crystal display, in which a physical barrier is created which prevents the flow of a liquid dye after application and ensures that individual cells are filled with only the desired color. Additionally, a means is disclosed which creates a surface with all colors initially present, followed by an exposure means and a development means which enables the desired color to fill the desired cell.
