Abstract:
The present invention provides a green coloring composition for use in a color filter, which can form a green colored film having low incident-angle dependence and improves the color-separation properties of a solid-state imaging device including the colored film; and a colored film, a color filter, and a solid-state imaging device. The green coloring composition for use in a color filter of the present invention is a green coloring composition for use in a color filter, containing a green colorant, a near-infrared absorbent, and a polymerizable compound, in which when the green coloring composition for use in a color filter is used to form a colored film having a film thickness of 0.8 μm, the maximum value of the transmittance at a wavelength from 400 nm to 450 nm of the colored film is 5% or less, the maximum value of the transmittance at a wavelength from 500 nm to 600 nm of the colored film is 70% or more, the minimum value of the transmittance at a wavelength from 650 nm to less than 700 nm of the colored film is 20% or less, and the minimum value of the transmittance at a wavelength from 700 nm to 900 nm of the colored film is 30% or less.
