Document Type and Number:
WIPO Patent Application WO/2022/044761
Kind Code:
A1
Abstract:
The present invention provides a composition containing semiconductor nanoparticles, said composition being capable of forming a wavelength conversion layer that efficiently converts the wavelength of excitation light and exhibits a sufficient luminous intensity. This composition containing semiconductor nanoparticles contains semiconductor nanoparticles (A), a (meth)acrylate compound (D) and a fluorescent dye (C), and is characterized in that: the semiconductor nanoparticles (A) have a maximum emission wavelength within the range of from 500 nm to 670 nm at a wavelength within the range of from 300 nm to 780 nm; the fluorescent dye (C) has a substituent that performs a function of linking to the semiconductor nanoparticles (A); and the content of the (meth)acrylate compound (D) in this composition containing semiconductor nanoparticles is 20% by mass or more.
