Abstract
A color filter and a fabrication method thereof are provided. In the method, color filter ink that includes wax beads is ejected by an inkjet printing process. A black matrix defining R/G/B pixels is formed on a first surface of a substrate and transparent electrodes are formed on a second surface of the substrate opposite to the first surface at positions corresponding to the R/G/B pixels. The fabricated color filter ink is injected into an inkjet head, and the color filter ink is ejected from the inkjet head into each of the R/G/B pixels. A predetermined voltage is applied between the inkjet head and the transparent electrode such that the ejected color filter ink is precisely injected into each of the R/G/B pixels.
