Abstract

Provided is a composition for forming a polarizer from which a polarizer with an excellent surface state can be formed, a polarizer, a laminate, and an image display device. The composition for forming a polarizer includes a polymerizable liquid crystal compound which has two or more rings selected from the group consisting of an aromatic ring and an alicyclic ring and two polymerizable groups and exhibits a liquid crystal state of a smectic phase, a monofunctional polymerizable compound which has two or more rings selected from the group consisting of an aromatic ring and an alicyclic ring and one polymerizable group, and a dichroic material, in which the number of atoms NA of the polymerizable liquid crystal compound and the number of atoms NB of the monofunctional polymerizable compound satisfy Expression (1), 0.35≤NB/NA≤0.65 (1).
