Transmission type screen

摘要

This is to provide a transmission type screen where a viewing angle at which an image projected by a projector can be visually recognized is extremely wide, and image visibility from the both surfaces of the screen is excellent.;The present invention relates to a transmission type screen comprising a light transmissive support and a light diffusion layer on at least one surface of the light transmissive support, wherein the light diffusion layer contains light diffusion fine particles and a xerogel. It preferably relates to the above-mentioned transmission type screen wherein the xerogel contains inorganic fine particles and a resin binder, and the inorganic fine particles are particles dispersed in an aggregated form having an average primary particle diameter of 18 nm or less and an average secondary particle diameter of 500 nm or less.
