Document Type and Number:
Japanese Patent JP6967443
Kind Code:
B2
Abstract:
To achieve both transparency and clearness of a projection image on a projection screen at high level.SOLUTION: A light scattering body 10 contains a resin medium 3 containing a resin, a first particle 1 which is dispersed in the resin medium 3 and has a median diameter of 50 nm or more and 360 nm or less, and a second particle 2 which is dispersed in the resin medium, has a median diameter of 500 nm or more and 1.5 μm or less, and has a diamond structure, in which the total content of the first particle and the second particle is 0.01 pts.mass or more and 20.0 pts.mass or less based on 100 pts.mass of the resin medium, a particle number ratio M/Mof a particle number Mof the first particles to a particle number Mof the second particles is 100 or more and 5,000 or less, and the total light transmittance of the light scattering body is 80% or more.SELECTED DRAWING: Figure 1
