ABSTRACT:
Methods of forming color filters having a light blocking material therebetween. A color filter is formed such that a trench is defined between a color filter and an adjacent color filter. The trench may be formed by exposing the color filter to polymerizing conditions such as, for example, ultraviolet radiation and heat. The trench may also be formed by etching between adjacent color filters. A material is formed within the trench.
