ABSTRACT:
The color filter manufacturing method for improving precision in correcting color unevenness of a screen surface by eliminating the influence of measurement errors and variance in the ink discharge amount, includes the steps of: coloring a coloring-target medium, using at least two different ink discharge densities, and measuring color densities of colored portions of the coloring-target medium; obtaining a relationship between the color density and ink discharge density based on the respective color densities of the colored portions colored by the at least two different ink discharge densities and corresponding ink discharge densities; and determining an ink discharge density which attains a desired color density based on the obtained relationship between the color density and ink discharge density, and discharging ink onto the color filter substrate at the determined ink discharge density, thereby coloring the color filter substrate.
