Abstract
A method of fabricating a black matrix of a color filter is provided. In the method, a black matrix layer formed of a hydrophobic organic material is formed on an upper surface of a transparent substrate. A black matrix is formed by patterning the black matrix layer. Side surfaces of the black matrix are made hydrophilic by irradiating a lower surface of the transparent substrate with ultraviolet rays while heating the black matrix. A black matrix provided by the method is also disclosed.
