Title:
LIGHT-DIFFUSING PARTICLES, LIGHT-DIFFUSING AND -TRANSMITTING SHEET, AND METHOD FOR PRODUCING LIGHT-DIFFUSING PARTICLES
Document Type and Number:
WIPO Patent Application WO/2018/142721
Kind Code:
A1
Abstract:
Light-diffusing particles (10) that comprise a core (10c) and a shell (10s). The core (10c) is formed from a first binder (11) and first fine particles (12). The first fine particles (12) include a low-refractive-index fine particle (12a) that has a lower refractive index than the first binder (11). The first fine particles (12) contact and are covered by the first binder. The shell (10s) contacts an outer surface of the core (10c) and covers the core (10c). The shell (10s) includes spherical particles (13) that have a particle diameter of 50–450 nm and give the shell (10s) surface roughness (A).
