摘要： PROBLEM TO BE SOLVED: To provide a large projection screen, which gives a wide viewing angle and a sharp image even in a corner of the screen when an image is projected onto the screen by a projector or the like, which can be used as both of a transmissive type and a reflective type, and which can be made nonflammable.
SOLUTION: The projection screen includes a substrate made of a transparent plastic or glass plate, and a light-diffusing layer having a thickness of 50 to 400 μm, which is formed on the surface of the substrate by using a transparent binder having a metal powder with an average particle diameter of 2 to 20 μm dispersed in a liquid resin, and repeating application of the transparent binder and heat-drying at least five times.
