Document Type and Number:

WIPO Patent Application WO/2020/004336

Kind Code:

A1

Abstract:

The present invention provides: a liquid composition containing quantum dots (A), which is suitable for the production of an optical film that has good fluorescence efficiency; a quantum dot-containing film which is obtained by drying and/or curing this liquid composition; an optical film for luminescent display elements, which is formed of this quantum dot-containing film; a luminescent display element panel which comprises this optical film; and a luminescent display device which is provided with this luminescent display element panel. According to the present invention, a liquid composition containing quantum dots (A) is configured to contain an ionic liquid (B) and a solvent (S) which contains a solvent (S1) that is a compound which has a cyclic skeleton, while containing a heteroatom other than a carbon atom and a hydrogen atom.
