Curable composition, light-shielding film, color filter, pattern forming method, method for manufacturing color filter, solid-state imaging element, and infrared sensor

Abstract

An object of the present invention is to provide a curable composition capable of forming a cured film having excellent linearity of a pattern, and a light-shielding film, a color filter, a solid-state imaging device, and an infrared sensor, each formed using the curable composition. Another object of the present invention is to provide a pattern forming method and a method for manufacturing a color filter, each using the curable composition. The curable composition of the present invention is a curable composition containing a visible light-absorbing coloring agent, an infrared ray-absorbing coloring agent, a polymerizable compound, and a photopolymerization initiator, in which a minimum value in optical densities per 1 μm of a film thickness in a wavelength range of 380 to 1,100 nm of a coating film of the curable composition is 1 or more, and the Δ optical density calculated by Formula (1) is 1 or less, ΔOptical density=|OD1−OD2|  Formula (1) in Formula (1), OD1 represents a minimum value in optical densities per 1 μm of a film thickness in a wavelength range from 380 nm to 780 nm of the coating film, and OD2 represents a minimum value in optical densities per 1 μm of a film thickness in a wavelength range of more than 780 nm and 1,100 nm or less of the coating film.
