Abstract
A method for forming black matrixes of a liquid crystal display device is provided that includes preparing a transparent substrate, printing first black matrixes on the substrate, and printing second black matrixes on the first black matrixes.
Claims10
A method for forming black matrixes in a liquid crystal display device comprising:
- providing a transparent substrate;
- printing first black matrixes on the substrate using a first printing roll;
- and
- printing second black matrixes on the first black matrixes using a second printing roll,
- wherein the first printing roll and the second printing roll are continuously rotating on the substrate to form continuously the first black matrixes and the second black matrixes.

A method for forming black matrixes in a liquid crystal display device comprising:
- providing first and second printing rollers having a plurality of convex patterns corresponding to patterns of the black matrixes to be formed;
- depositing a black matrix resin on the convex patterns;
- forming first black matrixes on a substrate by rotating the first printing roller across the surface of the substrate such that the black matrix resin deposited on the convex patterns of the first printing roller is transferred onto the substrate;
- and
- forming second black matrixes directly on the first black matrixes by rotating the second printing roller across the substrate such that the black matrix deposited on the convex patterns of the second printing roller is transferred onto the first black matrixes formed on the substrate,
- wherein the first printing roll and the second printing roll are continuously rotating on the substrate to form continuously the first black matrixes and the second black matrixes.
