Abstract
A method is presented for fabricating a color filter of a liquid crystal display (LCD) device without using a photo mask. The method includes providing a transparent substrate, depositing a color filter film on the substrate, forming a mask pattern which exposes a part of the color filter film, irradiating the surface of the color filter film, and applying developer to the color filter film to remove the unexposed color filter film and the mask pattern.
