Patent ID: 7291426

Claim:
A manufacturing method of a color filter, in which coloring matters are applied onto a transparent substrate on which surface a predetermined pattern of light-blocking bank functioning as a black matrix is formed, the manufacturing method of a color filter comprising the steps of: continuously discharging a coloring matter having photosensitivity from a nozzle to apply the coloring matter to between said light-blocking banks on the transparent substrate while, with a nozzle being scanned with respect to said transparent substrate, causing the transparent substrate and the nozzle to move intermittently at a predetermined pitch relatively in a direction orthogonal to said scanning direction; aligning and superimposing a mask in which a light transmission part corresponding to an active region of a color filter is formed on the backside of said transparent substrate, and exposing said transparent substrate to light from the backside through said mask 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 said transparent substrate to dissolve and remove the uncured coloring matter having been applied at a part corresponding to a non-active region of a color filter, and the uncured coloring matter having been applied onto said light-blocking bank.
