Title:
COMPOSITION CONTAINING SEMICONDUCTOR NANOPARTICLES, COLOR FILTER, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/161860
Kind Code:
A1
Abstract:
Provided is a composition containing semiconductor nanoparticles which is capable of forming wavelength conversion layers that efficiently convert the wavelengths of excitation light and exhibit a sufficient luminescent intensity. One embodiment of the composition containing semiconductor nanoparticles according to the present invention comprises semiconductor nanoparticles (A) and one or more colorants (B) and further contains a polymerizable compound (C), and is characterized in that the semiconductor nanoparticles (A), in the wavelength range of 300-780 nm, have a maximum-luminescence wavelength in the range of 500-670 nm and the colorants (B) comprise at least one colorant selected from among colorants (B1) to (B5) having specific structures.
