Patent ID: 7781129

Claim:
A photosensitive color composition for a color filter comprising a reactive substance involving a curing reaction and a coloring substance including a first and a second green pigments, wherein the first green pigment is one selected from the group consisting of green pigments for a color filter each of which is comprised of a phthalocyanine green pigment and capable of expressing a region of xy-chromaticity coordinate enclosed by the following Equations 1, 2 and 3 defined by the XYZ color system of the CIE when the green pigment is solely subjected to colorimetry using a F10 light source, and wherein the second green pigment is one selected from the group consisting of green pigments for a color filter each of which is comprised of a phthalocyanine green pigment and capable of expressing a region of xy-chromaticity coordinate enclosed by the following Equations 4, 5 and 6 defined by the XYZ color system of the CIE when the green pigment is solely subjected to colorimetry using a F10 light source: y= 2.640 Xx +0.080 (Equation 1) wherein a range of “x” in the Equation 1 is 0.180<x<0.230 y= 5261.500 Xx 4 −6338.700 Xx 3 +2870.400 Xx 2 −580.730 Xx +44.810 (Equation 2) wherein a range of “x” in the Equation 2 is 0.230<x<0.350 y=− 36.379 Xx 3 +37.410 Xx 2 −13.062 Xx +1.907 (Equation 3) wherein a range of “x” in the Equation 3 is 0.180<x<0.350 y= 8.000 Xx −1.513 (Equation 4) wherein a range of “x” in the Equation 4 is 0.260<x<0.270 y=− 1051.300 Xx 4 +1176.900 Xx 3 −450.880 Xx 2 +62.131 Xx −0.836 (Equation 5) wherein a range of “x” in the Equation 5 is 0.260<x<0.350 y= 5746.700 Xx 4 −7310.300 Xx 3 +3493.200 Xx 2 −744.610 Xx +60.251 (Equation 6) wherein a range of “x” in the Equation 6 is 0.270<x<0.350.
