ABSTRACT:
A method of manufacturing color filters in which a photosensitive film, which is used for forming filter elements, is formed on a substrate. A photomask with a given stripe pattern is placed above the photoresistive film. Under this condition, the photomasked-film is subjected to a first exposure process. The photomask is then moved in the direction of the stripes in the mask pattern. Following a second exposure process, developing, dyeing and dyeing-preventing processes are performed for color filter element formation. The foregoing steps are performed for each filter element for a specified color.
