ABSTRACT:
A manufacturing method of a color filter is capable of achieving improvement in efficiency of use of materials and simplification in process, and forming highly accurate colored patterns.The manufacturing method includes the steps of: continuously discharging a coloring matter from a nozzle to apply the coloring mater to between the banks12on the glass substrate while, with a nozzle being scanned with respect to a glass substrate10on which surface a predetermined pattern of light-blocking bank12is formed, intermittently feeding the glass substrate at a predetermined pitch in a direction orthogonal to the scanning direction; aligning and superimposing on the backside of the glass substrate a mask plate in which a light transmission part corresponding to an active region of a color filter is formed, and exposing the glass substrate to light from backside through the mask plate to cause a coloring matter having been applied at a part corresponding to an active region of the color filter to be cured; and developing the surface side of the glass substrate to dissolve and remove the uncured coloring matter having been applied at a part corresponding to the non-active region of a color filter.
