Abstract:
A green pigment for a color filter including a phthalocyanine green pigment and capable of expressing a region of xy-chromaticity coordinate enclosed by predetermined equations 1, 2 and 3 defined by the XYZ color system of the CIE when the green pigment is solely subjected to colorimetry. Moreover, using the above-mentioned green pigment, it provides a photosensitive color composition capable of forming a color filter having a wide color reproduction range and a high transmittance. Furthermore, it provides a color filter having a wide color reproduction range and a high transmittance with a green pixel formed using the above mentioned photosensitive color composition, and a liquid crystal panel using the color filter.
