Abstract: A reflection-type projection screen includes a substrate, a light-reflecting layer made from a transparent resin in which flakes of a light-reflective material are dispersed, and a transparent light-diffusing layer made from a transparent resin in which fine crystalline particles of calcite and an achromatic dye or pigment are dispersed. The surface of the light-diffusing layer functions as a projection-light-receiving, image-observation surface which receives the incident projection light and on which an image to be observed is formed. A lubricant can be incorporated into the light-diffusing layer. The calcite particles slightly absorb light and have moderate light-diffusing properties. As a result, the transmittance of the light-diffusing layer is increased. The light-reflecting layer has a high reflectance. Due to the synergistic effect of the properties of the two layers, the projection screen has a high reflection luminance (high gain).
