Abstract:
The present invention provides: a liquid composition which can be suitably used for production of an optical film having a favorable fluorescence efficiency and includes quantum dots (A), a quantum dot-containing film obtained by drying and/or curing the liquid composition, an optical film for a light-emitting display element made of the quantum dot-containing film, a light-emitting display element panel including the optical film, and a light-emitting display equipped with the light-emitting display element panel. An ionic liquid (B), and a solvent (S) are incorporated into a liquid composition including quantum dots (A), in which the solvent (S) includes a solvent (S1), the solvent (S1) being a compound having a cyclic skeleton and including a heteroatom other than a hydrogen atom and a carbon atom.
