Abstract
A method for making color filters for liquid crystal display panels. A raised pattern corresponding to the desired black matrix pattern is formed on a substrate, e.g., by an embossing means. A plurality of colored ink patterns is formed in the appropriate location within the boundaries formed by the raised pattern, thereby forming the multicolor image that will become the color filter.
