Abstract:
Provided are a near infrared absorbing composition with which a cured film having excellent solvent resistance and thermal shock resistance can be manufactured, a near infrared cut filter, a method of manufacturing a near infrared cut filter, a solid image pickup element, a camera module, and an image display device. The near infrared absorbing composition includes: a resin A that satisfies the following condition a1; an infrared absorber B; and a solvent D. At least the resin A has a crosslinking group, or the near infrared absorbing composition further includes a compound C having a crosslinking group that is different from the resin A. condition a1: in a case where the resin A does not have a crosslinking group, a glass transition temperature of the resin A measured by differential scanning calorimetry is 0° C. to 100° C., and in a case where the resin A has a crosslinking group, a glass transition temperature of a resin having a structure in which a portion which forms a crosslinking bond in the crosslinking group of the resin A is substituted with a hydrogen atom is 0° C. to 100° C., the glass transition temperature being measured by differential scanning calorimetry.
