Abstract
A pigment composition for a green filter includes a green pigment consisting of a halogenated zinc phthalocyanine, wherein as spectral transmission characteristics of a dispersion containing only the green pigment as a pigment, the transmittance at 400 nm is 1% or less; the transmittance at 450 nm is 25% or less; the transmittance at 600 nm is 30% or less; the transmittance at 650 nm is 0.3% or less; the transmittance at the peak wavelength is 80% or more; the half value width of the peak wavelength is 120 nm or less; the transmittance at 750 nm is 1% or less; and the transmittance at 800 nm is 20% or less. The pigment composition for a green filter has low transmittance in the blue range, low transmittance in the near infrared range, and high transmittance in the green range by only a green pigment.
