<p>A color filter which is better in durability than a dye-based color filter and has a green pixel unit that, when applied to a liquid crystal display unit using as a light source a three-band tube having a green-light main bright line of about 545 nm, enables a liquid crystal display giving dark yellow and bright green and being bright even with a back-light light source of a small light quantity. The color filter has the green pixel unit that is characterized in that (1) 8-16 halogen atoms per phthalocyamine molecule contain metal halide phthalocyamine pigment bonded to a phthalocyamine molecule benzene ring, and (2) it shows a maximum transmittance at 520-590 nm throughout a spectral transmission spectrum in the entire region of visible light.</p> |
