摘要

Composition capable of forming a film having good heat resistance and suppressing variation in spectral characteristics in the near-infrared region even under different humidity conditions during coating, film, near-infrared cut filter, and solid-state imaging device An image display device and an infrared sensor manufacturing method are provided. The composition includes a near-infrared absorbing compound A having a π-conjugated plane including a single ring or a condensed aromatic ring, and a solvent B. The solvent B has a solubility parameter of 19.9 MPa0.5 or more and 22.3 MPa0.5. Solvent B1 in the following range and Solvent B2 having a solubility parameter of less than 19.9 Pa0.5 or a solubility parameter exceeding 22.3 MPa0.5, and the content of Solvent B2 in Solvent B is It is 9 mass% or less.
