Title:
CURABLE COMPOSITION, FILM, OPTICAL FILM FOR LUMINESCENT DISPLAY ELEMENT, LUMINESCENT DISPLAY ELEMENT PANEL, AND LUMINESCENT DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/044879
Kind Code:
A1
Abstract:
Provided are: a liquid curable composition which contains quantum dots (A) and a curable substrate component (B) and which exhibits excellent dispersion stability of the quantum dots (A); a film comprising a cured product of the curable composition; an optical film for a luminescent display element, which is constituted of the film; a luminescent display element panel that includes the optical film; and a luminescent display device comprising the luminescent display element panel.　This curable composition contains the quantum dots (A) and the curable substrate component (B) and may contain a small amount of an organic solvent (S). A mercaptocarboxylic acid ester having a specific structure and having an alicyclic group having 5 or more ring-forming atoms is bound as a ligand to the surface of the quantum dots (A). A curable compound having a non-aromatic cyclic group having 5 or more ring-forming atoms is used as the curable substrate component (B).
