COLORANT COMPOSITION FOR A COLOR FILTER, COLOR FILTER USING THE SAME, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed is a photosensitive colorant composition containing: a green colorant including at least a halogenated zinc phthalocyanine pigment; a photopolymerizable monomer; a resin; a photopolymerization initiator; and a solvent. Said photopolymerizable monomer includes: either a polyfunctional urethane acrylate (constituting 15 to 45 wt%, inclusively, of the solid part of said photosensitive colorant composition) that has at least 0.7 x 10-3 mol/g of urethane groups and at least 4.5 x 10-3 mol/g of double bond groups, and that has a (meth) acryloyl group obtained by reacting a polyfunctional isocyanate with a (meth)acrylate having a hydroxyl group; or, dipentaerythritol pentaacrylate and dipentaerythritol hexaacrylate (constituting 10 to 25 wt%, inclusively, of the solid part of said photosensitive colorant composition). Furthermore, the voltage holding ratio of a liquid crystal display element provided with the color filter obtained by using said photosensitive colorant composition is no less than 90%.
