Abstract
A color filter of liquid crystal display (LCD) panel is described. A surface property of a black matrix is changed by coating with an ink-repellent layer formed of cheap materials, to provide better separation between portions of a colored layer, thus reducing the cost of the ink-repellent layer and avoid overflowing while color ink drops are attaching onto a transparent substrate. In addition, a method of fabricating a color filter of LCD panel is described. The ink-repellent layer is transferred onto the black matrix, and then the colored layer is formed thereon. The ink-repellent layer effectively separates the colored layer. This method of the invention greatly diminishes the usage of the ink-repellent layer, steps of exposure and development, and the cost and time of fabricating the color filter.
