There is provided a photoselective absorbing filter that does notnreduce the luminance of picture elements and is capable of efficientlynabsorbing reflected light and a color display device including such a filter.nThe transmittance of light at wavelengths of 470 to 510 nm and 550 to 600nnm relative to transmittance in the visible range other than those twonwavelength ranges is reduced, preferably by use of a coloring materialncontaining a pyridinophthalocyanine selected from metal tetra-2,3-pyridinoporphyrazines,nmetal tetra-3,4-pyridinoporphyrazines, tetra-2,3-pyridinoporphyrazinesnand tetra-3,4-pyridinoporphyrazines, and annanthraquinone dye suitably selected from Solvent Orange (35, 64, 65, 66, 68,n69, 71, 77, 86 and 87) and Solvent Red (52, 152, 155, 156, 168, 169, 170,n171, 172, 175, 177, 181, 190 and 191). |
