Abstract:
1. A method for correcting a micro defect in a color pattern of a color filter for a display comprising the steps of: applying, onto a small defect portion in a colored pattern of a color filter for a display, a correction ink for micro defect of a color pattern of a color filter for a display comprising a coloring agent, monomer having two or more ethylenic unsaturated bonds in a molecule, polymer and a solvent, wherein an amount of the solvent is from 25% by weight to 70% by weight of the whole ink and a viscosity of the ink is from 40 to 300 mPa·sec.; and after the applying step, radiating light thereon the small defect portion in the colored pattern to react the ethylenic unsaturated bond of the monomer, so that the correction ink is cured.
