Abstract
PURPOSE: To form the color filter of fine patterns directly on a substrate having undulations with good accuracy by using the one compounded with light absorptive material as the photosensitive resin for forming desired patterns through exposure and development treatment.
CONSTITUTION: The photosensitive resin (e.g, gelatin-ammonium dichromate base photoresist) compounded with the light-absorptive material (e.g., Tartrazine, tradename) which absorbs part of light of about 350W450nm, dissolves in the photosensitive resin and is dissolved and removed during development treatment is used. Namely, ultraviolet rays 10 are radiated through a mask 11 to the film 9 composed of the abovementioned photosensitive resin formed on a substrate 8 to expose the portions corresponding to the first color, thence it is developed with warm water to remove the unexposed portions of the film 9 and at the same time the light-absorptive material remained in the film 9 is eluted away, after which the portions 12 corresponding to the first color are dyed to the specified color, whereby the color filter is formed. Thence, a transparent intermediate layer 13 is provided, after which the operations similar to the above are accomplished subsequently, whereby the color filter of the second and subsequent colors are formed.
