Abstract
An object of the present invention is to provide a semiconductor nanoparticle-containing dispersion liquid having high initial luminous efficacy and exhibiting excellent moisture resistance; and a film produced using the dispersion liquid. The semiconductor nanoparticle-containing dispersion liquid of the present invention contains semiconductor nanoparticles from which zinc, sulfur, and indium are detected by X-ray photoelectron spectroscopy; and acrylate or methacrylate, in which a molar ratio of zinc to indium in the semiconductor nanoparticles which is acquired by the X-ray photoelectron spectroscopy satisfies Expression (1a).2.25<Zn/In<9  (1a)
