Abstract
(EN)
The present invention provides: a quantum dot-containing composition which has a particularly excellent pot life and contains a quantum dot suitable for mass production; a quantum dot-containing member in which the quantum dot-containing composition is used and, therefore, which has a high temporal durability; a backlight device; a display device; and a liquid crystal display element. The quantum dot-containing composition of the present invention is characterized by containing a polyfunctional (meth)acrylate, a polyfunctional thiol, a reaction retarder, and the quantum dot. In the present invention, the ratio between the number of moles of the (meth)acrylate group in the polyfunctional (meth)acrylate and the number of moles of the mercapto group in the polyfunctional thiol is preferably within the range of 0.6-9.0 inclusive. The quantum dot-containing member of the present invention is characterized by being obtained by curing the quantum dot-containing composition.
(FR)
La présente invention concerne : une composition contenant des points quantiques qui a une excellente durée de vie en pot et contient un point quantique approprié pour la production en masse ; un élément contenant des points quantiques dans lequel la composition contenant des points quantiques est utilisée et, par conséquent, qui a une durabilité temporelle élevée ; un dispositif de rétroéclairage ; un dispositif d'affichage ; et un élément d'affichage à cristaux liquides. La composition contenant des points quantiques de la présente invention est caractérisée en ce qu'elle contient un (méth)acrylate polyfonctionnel, un thiol polyfonctionnel, un retardateur de réaction et le point quantique. Dans la présente invention, le rapport entre le nombre de moles du groupe (méth)acrylate dans le (méth)acrylate polyfonctionnel et le nombre de moles du groupe mercapto dans le thiol polyfonctionnel est de préférence dans la plage de 0,6 à 9,0 inclus. L'élément contenant des points quantiques de la présente invention est caractérisé en ce qu'il est obtenu par le durcissement de la composition contenant des points quantiques.
