摘要： The present invention provides a color filter which is more durable than a dye-type color filter and also has green pixel portions which exhibit a bright green color having a strong yellowish tinge when used in a liquid crystal display device using a three-band lamp having a main emission line of green light of about 545 nm as a light source, thus enabling the liquid crystal display device to display bright images even when using a backlighting light source having a low intensity. This color filter comprises green pixel portions which (1) contain a halogenated metal phthalocyanine dye wherein 8 to 16 halogen atoms are bonded to benzene rings in one phthalocyanine molecule, and (2) exhibit maximum transmittance at a wavelength within a range from 520 nm to 590 nm with respect to the transmission spectra of the entire range of visible light.

摘要： 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.
