摘要

SUMMARY OF THE INVENTION An object of the present invention is to provide a curable composition capable of forming a cured film having excellent pattern linearity, a light shielding film formed using the curable composition, a color filter, a solid-state imaging device, and an infrared sensor. Another object of the present invention is to provide a pattern forming method using the curable composition and a method of manufacturing a color filter. The curable composition of the present invention is a curable composition containing a colorant that absorbs visible light, a colorant that absorbs infrared light, a polymerizable compound, and a photopolymerization initiator, The minimum value of the optical density per 1 占 퐉 of the film thickness in the region of the coating film of the curable composition at a wavelength of 380 to 1100 nm is 1 or more, The? Optical density obtained from the equation (1) is 1 or less. (1) Δ optical density = | OD1-OD2 | In the formula (1), OD1 represents the minimum value of the optical density per 1 占 퐉 of the film thickness in a region of the coating film having a wavelength of 380 nm or more and 780 nm or less, OD2 is the film thickness of 1 占 퐉 Represents the minimum value of the optical density of the sugar chain.
