Abstract
Color filter arrays containing one or more colors for liquid crystal displays and other optoelectronic devices are made by using a laser to ablate portions of a coating on either a colored or transparent substrate. Color filter materials are placed into the ablated openings and cured. The number of laser ablated openings in the coated substrate varies, depending on the quantity and types of colors desired.
