Provided is a curable composition which is capable of producing a cured film that has excellent line width stability. Also provided are: a cured film which is formed using such a curable composition; and a color filter, an optical element and a solid-state imaging element, each of which comprises this cured film. A curable composition according to the present invention contains a black colorant, a polymerizable compound, a resin A, a photopolymerization initiator and a polymerization inhibitor. With respect to this curable composition, the resin A satisfies one of the following requirements: the acid value thereof is 120-350 mgKOH/g; and the weight average molecular weight thereof is 3,000-7,500. |
