Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a quantum dot-containing composition having excellent pot life and containing quantum dots suitable for mass production, a quantum dot containing member excellent in temporal durability by using quantum dot-containing composition, a backlight device, a display device, and a liquid crystal display.

SOLUTION: The quantum dot-containing composition contains polyfunctional (meth) acrylate, polyfunctional thiol, reaction retarder, and quantum dots. In the quantum dot-containing composition, the ratio of the number of moles of (meth) acrylate groups of polyfunctional (meth) acrylate to the number of moles of mercapto groups of polyfunctional thiol is in a range of 0.6 or more and 9.0 or less. The quantum dot-containing member is composed of cured quantum dot-containing composition.
